- Click on Modify. 
 A dialog window is opened.
- Enable Hotkey, if not already enabled. 
- Select a modifier key or a combination of modifier keys under Modifiers. 
- Enter a Key. If you want to enter a key that has no visible character assigned, e. g. the [Tab] key, open a terminal, logon as user and enter- xev -event keyboard. Press the key designated for the hotkey. The text in brackets starting with- keysymwill contain the desired string for the Key field; example:- Tabin- (keysym 0xff09, Tab)
- Click on Ok. 
- Click on Apply or Ok. 
 The hotkey is ready for use.
