Assigning a speed key to a menu button or menu toggle lets the user press Alt plus a speed key rather than selecting the menu item. For a menu button, pressing the speed key combination executes the command. For a menu toggle, pressing the speed key combination switches the option between the on and off states.

Predefined speed keys can be associated with a menu item by using the Property Inspector to set the SpeedKey property. The physical key mappings for these logical keys can be different for each system. To assign your own logical key, select one of the SK_USER# options, where # is 1–36.
