Common Desktop Environment: Style Guide and Certification Checklist

Navigation

The desktop allows either BSelect or BMenu to be used to display menus. This capability has been added for users familiar with environments that provide a dedicated mouse menu button.

For mouse-based navigation of text fields, the desktop has added a requirement that the text cursor be placed at the mouse cursor position, rather than at the beginning or the end of the text field.

Mouse-Based Navigation

Optional 

b: 

BMenu Press or BMenu Click on a menu bar item displays the menu. 

Required 

c: 

BMenu Press or BMenu Click on an option button displays the option menu. 

Required 

d: 

BSelect Press on a text field causes the text cursor to be inserted at the mouse cursor position. 

Keyboard-Based Navigation

The requirement to support Tab as a navigation key within groups of push buttons has been added to make keyboard navigation easier for users who have difficulty with the standard keyboard. This change is intended to reduce the number of side-to-side traversals of the keyboard (from Tab to arrow keys and back) that a user must perform to navigate within a single dialog box.

Optional 

e: 

Each time a new window is opened, keyboard focus is placed in the first field or location within the window or in a default location, if this is appropriate for the particular window. 

Required 

f: 

The Tab key moves input focus between push buttons within a group. 

The arrow keys also move the selected focus per the OSF/Motif Style Guide, Revision 1.2. 

Required 

g: 

Use the Control, Shift, and Alt keys only to modify the function of other keys or key combinations. 

Optional 

h: 

Use the Alt key only to provide access to mnemonics.
