To modify the key combination in the Accelerator field, place the cursor in the Accelerator field and simple press the desired key combination. The text description of the key combination will automatically appear. To specify special hot key combinations, which you cannot normally type because the system will immediately interpret them using the default meaning, such as Alt+Tab, click Special Hot Key to open the Special Hot Key window. In the Keyboard Definition section, select the keys you want to use and click OK to return to the Keyboard Mapping window. The Accelerator field shows the new key combination.
