# Tips for Nyquist IDE

#

- In the Command Line Window, use Alt + Up and Alt + Down to retrieve recently entered commands. It can be retrieved up to last ten commands.

- In the Command Line Window, use Alt + Enter to begin a new line (for the purpose of inputting multiple lines). Only press Enter will send the input to the Nyquist kernel.

- In the Command Line Window or Document Window, double click or select the "Select Complete Paragraph" Item in the popup menu right before an open paren, the system will automatically select the text that begins with this open paren and ends with the corresponding close paren. This will be helpful for checking the matching parens or loading a complete function.

- In the Command Window or Document Window, select the "Load Selected Text" Item in the popup menu to load the selected text.

- The way the Paren Matching works: When type in a close paren, the cursor jumps to the corresponding open paren and blinks, then it returns to the close paren. The function can be disabled from the main menu.

- To plot sounds in a window, either type (s-plot ...) function in the Command Line Window/document to be loaded, or click the speed button S-Plot/through the menu Process-->S-Plot, a Plot Window will pop up and show the plots. Multiple Plot Windows can be displayed at the same time as the children windows of the program. There are some shortcut keys for the Plot Window: Shift + Mouse Drag to zoom in; Ctrl + Mouse Drag to pan (move the center of the view); Shift + Mouse Left Click to restore the original view of the plot; Mouse Right Click to pop up the menu. Advanced functions are listed in the pop up menu, including figure copy, view options, and zoom options.

- The program keeps the history of up to five most recently used (MRU) documents. And you can speedily reopen those MRU documents by getting through the menu File-->Reopen-->MRU List.

- The system working directory will be always set to the directory of the most recently opened document, no matter whether the document is opened from the open dialog or from the MRU List. It means that the temporary sound file and the plot file (if created) will be also created in that working directory.

- "Help Contents", "Topic Search" and "NyqIDE Tips" are local or online documentations. The program will first try to locate the documentations locally. If failed, the program will try to locate the online documentations.

- Function keys F2-F12 are related to the functions with the same key names. E.g. Press F2 (or click the speed button F2 or go through the menu Process-->Function Keys-->Function F2) is equivalent to typing "(F2)" in the Command Line Window. However, pressing F1 will display the "Topic Search" documentation.

- We welcome your suggestion to improve this program. This program was made in order to let Nyquist easier to use and friendlier to the programmers.
