Map-to-Button and Functional Hot Keys
There are two types of hot keys: map-to-button and functional hot keys.
Map-to-button hot keys are keystroke sequences that are mapped to a button or a field on the current menu. You can create and edit as many map-to-button hot keys as you like. You can even assign a hot key to options in a pop-up menu.
Functional hot keys are predefined hot keys for specific functions. You cannot create new functional hot keys, but you can redefine and remap the ones provided with the system.
