Keyboard (Device)

Use equivalent, though not necessarily identical, mouse and keyboard techniques to provide access to all functions.

Use Ctrl, Shift, and Alt only to modify the function of other keys or key combinations on the keyboard or pointing-device actions.

Use Alt in conjunction with printing characters only to provide access to mnemonics in an application or for predefined actions. For information on bidirectional and vertical language support, see Chapter 11.

If the functions listed in Appendix B are provided, assign them to the keys listed in the table. Do not assign these functions to other keys. Only the user should reassign them.
