VIMB(1)

NAME
Vimb - Vim Browser - A modal web browser based on WebKit, inspired by Vim: the great editor.

SYNOPSIS
vimb [OPTIONS] [URI|file|-]

DESCRIPTION
Vimb is a WebKit based web browser that behaves like the Vimperator plugin for Firefox and has usage paradigms from the great editor, Vim. The goal of Vimb is to build a completely keyboard-driven, efficient and pleasurable browsing-experience.

OPTIONS
If no URI or file is given, Vimb will open the configured home-page. If URI is '-', Vimb reads the HTML to display from stdin.

Mandatory arguments to long options are mandatory for short options too.

-C, --cmd CMD
    Run CMD as ex command line right before the first page is loaded. If the flag is used more than one time, the commands are called in order they are given. You could also pass several ex commands in one CMD, if they are separated by "|".

        vimb --cmd "set dark-mode=on|set header=Referer,DNT=1"

-c, --config FILE
    Use custom configuration given as FILE. This will also be applied on new spawned instances.

-e, --embed WINID
    WINID of an XEmbed-aware application, that Vimb will use as its parent.

-i, --incognito
    Start an instance with user data read-only (see FILES section).

-h, --help
    Show help options.

-p, --profile PROFILE-NAME
    Create or open specified configuration profile. Configuration data for the profile is stored in a directory named PROFILE-NAME under default directory for configuration data.

-v, --version
    Print build and version information and then quit.

--no-maximize
    Do no attempt to maximize window.

--bug-info
    Prints information about used libraries for bug reports and then quit.

MODES
Vimb is modal and has the following main modes:

Normal Mode
    The default mode. Pressing Escape always enter normal mode.

Input Mode
    Used for editing text elements in a webpage.

Command Mode
    Execute `ex` commands from the builtin inputbox (commandline).

Pass-Through Mode
    In Pass-Through mode only the `<Esc>` and `<C-[>` keybindings are interpreted by Vimb, all other keystrokes are given to the webview to handle them. This allows the use of a website's configured keybindings, that might otherwise be swallowed by Vimb.

NORMAL MODE COMMANDS
Some of the Normal Model Commands can have a numeric count to multiply the effect of the command. If a command supports the count this is shown as [N].

  General

:   Start Command Mode and print `:' to the input box.

gi  Set cursor to the first editable element in the page and switch to Input Mode.

i   Set cursor to the last focused element in the page and switch to Input Mode. If no element was focused before the first element is focused like with `gi'.

CTRL-Z

'{A-Z}
    Jump to the global mark {A-Z} on a (possibly) different page.

''  Jumps to the position before the latest jump, or where the last "m'" command was given.

  Hinting
Hinting in Vimb is how you accomplish the tasks that you would do with the mouse in common mouse-driven browsers: open a URI, yank a URI, save a page and so on. When hinting is started, the relevant elements on the page will be marked by labels generated from configured `hint-keys'. Hints can be selected by using <Tab>, <C-I> or <C-Tab>, <C-O>, by typing the chars of the label, or filtering the elements by some text that is part of the hinted element (like URI, link text, button label) or any combination of these methods. If <enter> is pressed, the current active hint will be fired. If only one possible hint remains, this will be fired automatically.

Syntax: ;{mode}{hint}

Start Hints mode. Different elements depending on mode are highlighted and `numbered'. Elements can be selected either by typing their label, or by typing part of their text (hint) to narrow down the result. When an element has been selected, it is automatically clicked or used (depending on mode) and hint mode ends.

The filtering of hints by text splits the query at ' ' and use the single parts as separate queries to filter the hints. This is useful for hints that have a lot of filterable chars in common and many chars are required to make a distinct selection. For example ';over tw' will easily select the second hint out of {'very long link text one', 'very long link text two'}.

The following keys have special meanings in Hints modes:
<CR>
    Selects the first highlighted element, or the current focused.
<Tab>
    Moves the focus to the next hint element.
<S-Tab>
    Moves the focus to the previous hint element.
<Esc>, CTRL-C, CTRL-[
    Exits Hints mode without selecting an element.

Hint modes:
    f   Is an alias for the ;o hint mode.
    F   Is an alias for the ;t hint mode.
    ;o  Open hint's location in the current window.
    ;t  Open hint's location in a new window.
    ;s  Saves the hint's destination under the configured `download-path'.
    ;O  Generate an `:open' prompt with hint's URI.
    ;T  Generate an `:tabopen' prompt with hint's URI.
    ;e  Open the configured editor (`editor-command') with the hinted form element's content. If the file in editor is saved and the editor is closed, the file content will be put back in the form field.
    ;i  Open hinted image in the current window.
    ;I  Open hinted image in a new window.
    ;k  Kill (remove) hinted element from the page.
    ;p  Push the hint's URI to the end of the Read It Later queue like the `:qpush' command. This is only available if Vimb was compiled with the QUEUE feature.
    ;P  Push the hint's URI to the beginning of the Read It Later queue like the `:qunshift' command. This is only available if Vimb was compiled with the QUEUE feature.
    ;x  Hints like ;o, but instead of opening the hinted URI, the `x-hint-command' is run in Vimb.
    ["x];y
        Yank hint's destination location into primary and secondary clipboard and into the register x.
    ["x];Y
        Yank hint's text description or form text into primary and secondary clipboard and into the register x.

Syntax: g;{mode}{hint}
    Start an extended hints mode and stay there until <Esc> is pressed. Like normal hinting, except that after a hint is selected, hints remain visible so that another one can be selected with the same action as the first. Note that the extended hint mode can only be combined with the following hint modes I o p P s t y Y.

Motion
    Motions commands are like those for normal mode except that CTRL is used as modifier. But they can not be used together with a count.

    CTRL-F
        Scroll one page down.
    CTRL-B
        Scroll one page up.
    CTRL-D
        Scroll half page down.
    CTRL-U
        Scroll half page up.
    CTRL-J
        Scroll one step down.
    CTRL-K
        Scroll one step up.

  Searching

/QUERY, ?QUERY
    Start searching for QUERY in the current page. / start search forward, ? in backward direction.

*, #
    Start searching for the current selected text, or if no text is selected for the content of the primary or secondary clipboard. * start the search in forward direction and # in backward direction.

    Note that these commands will yank the text selection into the clipboard and may remove other content from there!

[N]n
    Search for Nnth next search result depending on current search direction.

[N]N
    Search for Nnth previous search result depending on current search

<CR>
    Perform a click on element containing the current highlighted search result. direction.

  Zooming

[N]zi
    Zoom-In the text of the page by N steps.

[N]zo
    Zoom-Out the text of the page by N steps.

[N]zI
    Full-Content Zoom-In the page by N steps.

[N]zO
    Full-Content Zoom-Out the page by N steps.

zz  Reset Zoom.

  Yank

["x]y
    Yank the URI or current page into register x and clipboard.

["x]Y
    Yank the current selection into register x and clipboard.

COMMAND MODE
Commands that are listed below are ex-commands like in Vim, that are typed into the inputbox (the command line of vimb). The commands may vary in their syntax or in the parts they allow, but in general they follow a simple syntax.

Syntax: :[:| ][N]cmd[name][!][ lhs][ rhs]

Where lhs (left hand side) must not contain any unescaped space. The syntax of the rhs (right hand side) if this is available depends on the command. At the moment the count parts [N] of commands is parsed, but currently there is no command that uses the count.

Commands that are typed interactivly are normally recorded into command history and register. To avoid this, the commands can be prefixed by one or more additional `:' or whitespace.

Multiple commands, separated by a `|' can be given in a single command line and will be executed consecutively. The pipe can be included as an argument to a command by escaping it with a backslash.
Following commands process the entire command-line string literally. These commands will include any `|' as part of their argument string and so can not be followed by another command.

-   autocmd
-   cmap, cnoremap, imap, inoremap, nmap, nnoremap
-   eval
-   normal
-   open, tabopen
-   shellcmd

  Command Line Editing

<Esc>, CTRL-[, CTRL-C
    Ignore all typed content and switch back to normal mode.

<CR>
    Submit the entered `ex` command or search query to run it.

CTRL-H
    Deletes the char before the cursor.

CTRL-W
    Deletes the last word before the cursor.

CTRL-U
    Remove everything between cursor and prompt.

CTRL-B
    Moves the cursor directly behind the prompt `:'.

CTRL-E
    Moves the cursor after the prompt in inputbox.

CTRL-V
    Pass the next key press directly to GTK.

CTRL-R {a-z"%:/;}
    Insert the content of given register at cursor position. See also section about `:reg[ister]' command.

  Command Line History

<Tab>
    Start completion of the content in the inputbox in forward direction.

<S-Tab>
    Start completion of the content in the inputbox in backward direction.

<Up>
    Step backward in the command history.

<Down>
    Step forward in the command history. Yank the current selection into register x and clipboard.

  Open

:o[pen] [URI]
    Open the give URI in the current window. If URI is empty, the configured 'home-page' is opened.

:t[abopen] [URI]
    Open the give URI in a new window. If URI is empty, the configured 'home-page' is opened.

  Key Mapping
Key mappings allow users to alter the actions of key presses. Each key mapping is associated with a mode and only has effect when the mode is active. The following commands allow the user to substitute one sequence of key presses by another.

Syntax: :{m}map {lhs} {rhs}

Note that the lhs ends with the first found space. If you want to use space also in the {lhs} you have to escape this with a single '\', as shown in the examples.

The rhs starts with the first non-space char. If you want a rhs that starts with a space, you have to use "<Space>".

Standard key mapping commands are provided for these modes m:
n   Normal mode: when browsing normally.
i   Insert mode: when interacting with text fields on a website.
c   Command Line mode: when typing into Vimb's command line.

Most keys in key sequences are represented simply by the character that you see on the screen when you type them. However, as a number of these characters have special meanings, and a number of keys have no visual representation, a special notation is required.

As special key names have the format <...>. The following special keys can be used: <Left>, <Up>, <Right>, <Down> for the cursor keys, <Tab>, <Esc>, <CR>, <Space>, <BS>, <F1>-<F12> and <C-A>-<C-Z>. If you want an actual sequence of keys like "<", "C", "R", ">" then escape with a backslash: "<CR>". If you want a backslash followed by a special key then use <Bslash>.

:nm[ap] {lhs} {rhs}
:im[ap] {lhs} {rhs}
:cm[ap] {lhs} {rhs}
    Map the key sequence lhs to rhs for the modes where the map command applies. The result, including rhs, is then further scanned for mappings. This allows for nested and recursive use of mappings.

    :cmap <C-G>h /home/user/downloads/
        Adds a keybind to insert a file path into the input box. This could be useful for the `:save' command that could be used as ":save ^Gh".
    :nmap <F1> :set scripts=on<CR>:open !glib<Tab><CR>
        This will enable scripts and lookup the first bookmarked URI with the tag `glib' and open it immediately if F1 key is pressed.
    :nmap \ \  50G
        Example which maps two spaces to go to 50% of the page.
:nn[oremap] {lhs} {rhs}
:ino[remap] {lhs} {rhs}
:cno[remap] {lhs} {rhs}
    Map the key sequence lhs to rhs for the mode where the map command applies. Disallow mapping of rhs, to avoid nested and recursive mappings. Often used to redefine a command.
:nu[nmap] {lhs}
:iu[nmap] {lhs}
:cu[nmap] {lhs}
    Remove the mapping of lhs for the applicable mode.

  Bookmarks

:bma [tags]
    Save the current opened URI with tags to the bookmark file.

:bmr [URI]
    Removes all bookmarks for given URI or, if not given, the current opened page.

  Handlers
Handlers allow specifying external scripts to handle alternative URI methods.

:handler-add handler=cmd
    Adds a handler to direct handler links to the external cmd. The cmd can contain one placeholder `%s` that will be filled by the full URI given when the command is called.

    :handler-add mailto=urxvt -e mutt %s
        to start email client for mailto links.
    :handler-add magnet=xdg-open %s
        to open magnet links with xdg-open.
    :handler-add ftp=urxvt -e wget %s -P ~/ftp-downloads
        to handle ftp downloads via wget.

:handler-remove handler
    Remove the handler for the given URI handler.

  Shortcuts
Shortcuts allow the opening of an URI built up from a named template with additional parameters. If a shortcut named 'dd' is defined, you can use it with `:open dd list of parameters' to open the generated URI.

Shortcuts are convenient to use with search engines where the URI is standardised and a single parameter is user defined.

:shortcut-add shortcut=URI
    Adds a shortcut with the shortcut and URI template. The URI can contain multiple placeholders $0-$9 that will be filled by the parameters given when the shortcut is called. The parameters given when the shortcut is called will be split into as many parameters like the highest used placeholder.

    To use spaces within the parameters, the parameters can be grouped by surrounding them with single-or double quotes-as shown in example shortcut `map'.

    :shortcut-add dl=https://duckduckgo.com/lite/?q=$0
        to setup a search engine. Can be called by `:open dl my search phrase'.
    :shortcut-add gh=https://github.com/$0/$1
        to build URIs from given parameters. Can be called `:open gh fanglingsu vimb'.
    :shortcut-add map=https://maps.google.com/maps?saddr=$0&daddr=$1
        to search for a route, all but the last parameter must be quoted if they contain spaces like `:open map "city hall, London" railway station, London'

:shortcut-remove shortcut
    Remove the search engine to the given shortcut.

:shortcut-default shortcut
    Set the shortcut for given shortcut as the default, that is the shortcut to be used if no shortcut is given and the string to open is not an URI. It doesn't matter if the shortcut is already in use or not to be able to set it.

  Settings

:se[t] var=value
    Set configuration values named by var. To set boolean variable you should use 'on', 'off' or 'true' and 'false'. Colors are given as hexadecimal value like '#f57700'. Spaces or more equals signs in value just work without quotes: for example, ":set sans-serif-font=Some Sans Font".

:se[t] var+=value
    Add the value to a number option, or append the value to a string option. When the option is a comma separated list, a comma is added, unless the value was empty.

:se[t] var^=value
    Multiply the value to a number option, or prepend the value to a string option. When the option is a comma separated list, a comma is added, unless the value was empty.

:se[t] var-=value
    Subtract the value from a number option, or remove the value from a string option, if it is there. When the option is a comma separated list, a comma is deleted, unless the option becomes empty.

:se[t] var?
    Show the current set value of variable. VAR.

:se[t] var!
    Toggle the value of boolean variable var and display the new set value.

  Queue
The queue allows the marking of URIs for later reading. This list is shared between the single instances of Vimb.

:qpu[sh] [URI]
    Push URI or, if not given, the current URI to the end of the queue.

:qun[shift] [URI]
    Push URI or, if not given, the current URI to the beginning of the queue.

:qp[op]
    Open the oldest queue entry in the current browser window and remove it from the queue.

:qc[lear]
    Removes all entries from queue.

  Automatic commands
An autocommand is a command that is executed automatically in response to some event, such as a URI being opened. Autocommands are very powerful. Use them with care and they will help you avoid typing many commands.

Autocommands are built with following properties.

group
    When the [group] argument is not given, Vimb uses the current group as defined with ':augroup', otherwise, Vimb uses the group defined with [group]. Groups are useful to remove multiple grouped autocommands.

event
    You can specify a comma separated list of event names. No white space can be used in this list.

    Events:
    LoadStarting
        Fired before a new page is going to be opened. No data has been sent or received yet, the load may still fail for transport issues.
    LoadStarted
        Fired if a new page is going to be opened. No data has been received yet, the load may still fail for transport issues.
    LoadCommitted
        Fired if first data chunk has arrived, meaning that the necessary transport requirements are established, and the load is being performed. This is the right event to toggle content related setting like 'scripts', 'plugins' and such things.
    LoadFinished
        Fires when everything that was required to display on the page has been loaded.
    DownloadStarted
        Fired right after a download is started.
    DownloadFinished
        Fired if a Vimb managed download is finished.
    DownloadFailed
        Fired if a Vimb managed download failed.

pat Comma separated list of patterns, matches in order to check if a autocommand applies to the URI associated to an event. To use ',' within the single patterns this must be escaped as '\,'.

    Patterns:
    *   Matches any sequence of characters. This includes also '/' in contrast to shell patterns.
    ?   Matches any single character except of '/'.
    {one,two}
        Matches 'one' or 'two'. Any '{', ',' and '}' within this pattern must be escaped by a '\'. '*' and '?' have no special meaning within the curly braces.
    \   Use backslash to escape the special meaning of '?*{},' in the pattern or pattern list.

cmd Any `ex` command vimb understands. The leading ':' is not required. Multiple commands can be separated by '|'.

:au[tocmd] [group] {event} {pat} {cmd}
    Add cmd to the list of commands that Vimb will execute automatically on event for a URI matching pat autocmd-patterns. Vimb always adds the cmd after existing autocommands, so that the autocommands are executed in the order in which they were given.

:au[tocmd]! [group] {event} {pat} {cmd}
    Remove all autocommands associated with event and which pattern match pat, and add the command cmd. Note that the pattern is not matched literally to find autocommands to remove, like Vim does. Vimb matches the autocommand pattern with pat. If [group] is not given, deletes autocommands in current group, as noted above.

:au[tocmd]! [group] {event} {pat}
    Remove all autocommands associated with event and which pattern matches pat in given group (current group by default).

:au[tocmd]! [group] * {pat}
    Remove all autocommands with patterns matching pat for all events in given group (current group by default).

:au[tocmd]! [group] {event}
    Remove all autocommands for event in given group (current group by default).

:au[tocmd]! [group]
    Remove all autocommands in given group (current group by default).

:aug[roup] {name}
    Define the autocmd group name for the following ":autocmd" commands. The name "end" selects the default group.

:aug[roup]! {name}
    Delete the autocmd group name.

Example:
    :aug github
    :  au LoadCommitted * set scripts=off|set cookie-accept=never
    :  au LoadCommitted http{s,}://github.com/* set scripts=on
    :aug end

  Misc

:cl[eardata] [dataTypes] [timespan]
    Asynchronously clears the website data of the given list of dataTypes modified in the past timespan. Note that the dataTypes must not contain spaces. If timespan is not given, all website data will be removed. Note that this effects all running instances of vimb.

    The dataTypes is a comma separated list of following types.
    memory-cache
        Memory cache.

        :sh! /bin/sh -c 'echo "`date` $VIMB_URI" >> myhistory.txt'

:sh[ellcmd] cmd
    Runs the given shell cmd syncron and print the output into inputbox. The following patterns in cmd are expanded: '~username', '~/', '$VAR' and '${VAR}'. A '\' before these patterns disables the expansion.

    The following environment variables are set for called shell commands.
    VIMB_URI
        This variable is set by Vimb every time a new page is opened to the URI of the page.
    VIMB_SELECTION
        This variable is set to the current selected text on the page.
    VIMB_TITLE
        Contains the title of the current opened page.
    VIMB_PID
        Contains the pid of the running Vimb instance.
    VIMB_WIN_ID
        Holds the X-Window id of the Vimb window.
    VIMB_XID
        Holds the X-Window id of the Vimb window or of the embedding window if Vimb is compiled with XEMBED and started with the -e option.
:sh[ellcmd]! cmd
    Like :sh[ellcmd] but asynchronous.

    Example:
        :sh! /bin/sh -c 'echo "`date` $VIMB_URI" >> myhistory.txt'
:s[ave] [path]
    Download current opened page into configured download directory. If path is given, download under this file name or path. path is expanded and can therefore contain '~/', '${ENV}' and '~user' pattern.

    "a — "z
        26 named registers "a to "z. Vimb fills these registers only when you say so.
    ":  Last executed `ex` command.
    ""  Last yanked content.
    "%  Curent opened URI.
    "/  Last search phrase.
    ";  Contains the last hinted URL.

:e[val] javascript
    Runs the given javascript in the current page and display the evaluated value.

    Example: :eval document.cookie

:e[val]! javascript
    Like :eval, but there is nothing print to the input box.

:no[rmal] [cmds]
    Execute normal mode commands cmds. This makes it possible to execute normal mode commands typed on the input box.

    cmds cannot start with a space. Put a count of 1 (one) before it, "1 " is one space.

    Example: :set scripts!|no! R

:no[rmal]! [cmds]
    Like :normal, but no mapping is applied to cmds.

:ha[rdcopy]
    Print current document. Open a GUI dialog where you can select the printer, number of copies, orientation, etc.

INPUT MODE

<Esc>, CTRL-[
    Switch back to normal mode.

CTRL-O
    Executes the next command as normal mode command and return to input mode.

CTRL-T
    Open configured editor with content of current form field.

CTRL-V
    Pass the next key press directly to WebKit.

CTRL-Z
    Enter the pass-through mode.

COMPLETIONS
The completions are triggered by pressing `<Tab>` or `<S-Tab>` in the activated inputbox. Depending of the current inserted content different completions are started. The completion takes additional typed chars to filter the completion list that is shown.

commands
    The completion for commands are started when at least `:` is shown in the inputbox. If initial chars are passed, the completion will lookup those commands that begin with the given chars.

settings
    The setting name completion is started if at least `:set ` is shown in inputbox and does also match settings that begins with already typed setting prefix.

history
    The history of URIs is shown for the `:open ` and `:tabopen ` commands. This completion looks up every given word in the history URI and titles. Only those history items are shown, where the title or URI contains all tags.

    :open foo bar<Tab>
        will complete only URIs that contain the words foo and bar.

bookmarks
    The bookmark completion is similar to the history completion, but does match only the tags of the bookmarks. The bookmark completion is started by `:open !`, `:tabopen !` or `:bmr ` and does a prefix search for all given words in the bookmark tags.

    :open !foo ba
        will match all bookmarks that have tags starting with "foo" and "ba". If the bookmark does not have any tags set, the URL is split on `.' and `/' into tags.

    :bmr tag
        will match all bookmarks that have tags starting with "tag".

bookmark tags
    The bookmark tag completion allows the insertion of already used bookmarks for the `:bma ` commands.

search
    The search completion allows a filtered list of already done searches. This completion starts by `/` or `?` in inputbox and performs a prefix comparison for further typed chars.

SETTINGS
All settings listed below can be set with the `:set' command. See Settings under COMMAND MODE for syntax.

dns-prefetching (bool)
    Indicates if Vimb prefetches domain names.

download-command (string)
    A command with placeholder '%s' that will be invoked to download a URI in case 'download-use-external' is enabled.

    The following additional environment variable are available:
    $VIMB_URI
        The URI of the current opened page, normally the page where the download was started from, also known as referer.
    $VIMB_DOWNLOAD_PATH
        Setting value of 'download-path' which would be used normally for downloads.

    :set download-command=/bin/sh -c "cd '$VIMB_DOWNLOAD_PATH' && curl -sLJOC - -e '$VIMB_URI' %s"

download-path (string)
    Path to the default download directory. If no download directory is set, download will be written into current directory. The following pattern will be expanded if the download is started '~/', '~user', '$VAR' and '${VAR}'.

download-use-external (bool)
    Indicates if the external download tool set as 'download-command' should be used to handle downloads. If this is disabled Vimb will handle the download.

editor-command (string)
    Command with placeholder '%s' called if form field is opened with $EDITOR to spawn the editor-like `x-terminal-emulator -e vim %s'. To use Gvim as the editor, it's necessary to call it with `-f' to run it in the foreground.

font-size (int)
    The default font size used to display text.

frame-flattening (bool)
    Whether to enable the Frame Flattening. With this setting each subframe is expanded to its contents, which will flatten all the frames to become one scrollable page.

    Show the current window full-screen.

hardware-acceleration-policy (string)
    This setting decides how to enable and disable hardware acceleration.
    ondemand
        enables the hardware acceleration when the web contents request it, disabling it again when no longer needed.
    always
        enforce hardware acceleration to be enabled.
    never
        disables it completely. Note that disabling hardware acceleration might cause some websites to not render correctly or consume more CPU.

header (list)
    Comma separated list of headers that replaces default header sent by WebKit or new headers. The format for the header list elements is `name[=[value]]'.

    Note that these headers will replace already existing headers. If there is no '=' after the header name, then the complete header will be removed from the request, if the '=' is present means that the header value is set to empty value.

    Note that webkit reused already set headers in case of a reload of a page. So if there are headers removed that where previously use to access a certain page and the page is reloaded or opened via back/forward history the header will still be sent. To apply the new header setting properly it's required to request another page or to open current page new by `O<Cr>`.

    To use '=' within a header value the value must be quoted like shown in Example for the Cookie header.

    :set header=DNT=1,User-Agent,Cookie='name=value'
        Send the 'Do Not Track' header with each request and remove the User-Agent Header completely from request.

hint-follow-last (bool)
    If on, vimb automatically follows the last remaining hint on the page. If off hints are fired only if enter is pressed.

hint-keys-same-length (bool)
    If on, all hint labels will have the same length, so no hints will be ambiguous.

hint-timeout (int)
    Timeout before automatically following a non-unique numerical hint. To disable auto fire of hints, set this value to 0.

hint-keys (string)
    The keys used to label and select hints. With its default value, each hint has a unique label which can be typed to select it, while all other characters are used to filter hints based on their text. With a value such as asdfg;lkjh, each hint is `labeled' based on the characters of the home row.

    If the hint-keys string starts with a '0' the keys are considered to follow the rules of numeric labeling. So that the ifrst char of the label will never start with the '0'.

    Note that the hint matching by label built of hint-keys is case sensitive. In this vimb differs from some other browsers that show hint labels in upper case, but match them lowercase.

    To have upper case hint labels, it's possible to add following css to the `style.css' file in vimb's configuration directory.

    "span[vimbhint="label"] {text-transform: uppercase !important;}"

hint-match-element (bool)
    If this is set to 'true' typed chars that are not part of the set 'hint-keys' are used to filter hinted DOM elements by their text value. If 'hint-keys' are set to chars instead of numbers it might be useful to disable matching of the elements by 'hint-match-element=false'.

history-max-items (int)
    Maximum number of unique items stored in search-, command or URI history. If history-max-items is set to 0, the history file will not be changed. This setting has no effect if option --incognito is set.

home-page (string)
    Homepage that vimb opens if started without a URI.
