2.2.2.5-5 Menu Selection by Pointing

When menu selection is the primary means of command entry, and especially if choices must be made from extensive lists of displayed control options, option selection by direct pointing should be provided.

Additional Information:
If a capability for direct pointing is not provided (e.g., if pointing involves separate manipulation of a mouse, or cursor positioning by key action), then for long menus it may prove faster to permit menu selection by keying associated option codes. Pointing directly at a displayed option guarantees good display-control compatibility. Users do not have to note associated option codes and enter them by key actions.
