This test is for unix platforms only. Press OK if you are not testing on those platforms. Before the test, you need to modify the keyboard mapping for X by issueing the following command: xmodmap -e 'keycode 60 = aacute' (this is for Solaris Sparc keyboard) xmodmap -e 'keycode 23 = aacute' (this is for Linux PC keyboard) This command lets you type 'a with acute' character when you press 'Tab' keytop. Please do not fail to restore the original key mapping by doing the following after the test xmodmap -e 'keycode 60 = Tab' (this is for Solaris Sparc keyboard) xmodmap -e 'keycode 23 = Tab' (this is for Linux PC keyboard) Confirm the following two behaviors: "KEYPRESS received for aacute" is displayed when you press 'Tab' keytop. On Solaris Sparc keyboard, The key sequence ("Compose", "a", "'") generates a-acute character in en_US locale
