Shortcut Key

Provide the predefined shortcut key assignment for each predefined choice.

When the user presses a shortcut key, perform the same function that would be performed if the user had activated the associated choice.

Perform the function assigned to a shortcut key only if it is assigned within the active window.

If the shortcut key choice is within a menu displayed from a menu bar, activate the choice if the user presses the shortcut key and the input focus is in the menu-bar system or the window that contains the menu bar.

If the shortcut key choice is on a push button, activate the choice if the user presses the shortcut key and the active cursor is in the window.

If the shortcut key choice is within a pop-up menu system, activate the choice if and only if that pop-up menu system is active or the pop-up menu is associated with the active cursor.

Even if the user turns off the display of shortcut keys in a menu, continue to support the shortcut keys that correspond to the menu items.

Do not use a printing character augmented by Alt as a shortcut key, as it would conflict with activation that uses mnemonics.

Assign the same shortcut key for a choice in all windows that provide that choice.

If the user can change shortcut key assignments, display the new assignments in menus and list the new assignments in any Help information provided for the shortcut keys.
