The interface supports keyboard mnemonics and the use of the arrow keys to move
within or between menus. For each menu or menu item, the underlined character
in the menu or menu item label is the keyboard mnemonic character. Notice the
keyboard mnemonic is not always the first character of the label. If a menu item
has a cascade menu attached to it, then typing the keyboard mnemonic displays the
cascade menu.
Some menu items have an ellipsis ("...") as part of the menu label. An ellipsis
indicates that the menu item will display a dialog or other box when the menu item
is chosen.
Dialog boxes support the use of the keyboard as well. To direct keyboard input to
a dialog box, you must position the mouse pointer somewhere inside the
boundaries of the dialog box. That is because the interface keyboard focus policy is
set to pointer. That just means that the window containing the mouse pointer
receives the keyboard input.
In addition to keyboard mnemonics, you can also specify keyboard accelerators
which are keyboard shortcuts for selected menu items. Refer to Chapter 10,
"Setting X Resources", and the "Softkey.Input" scheme file for more information
about setting the X resources that control defining keyboard accelerators.
