HotKeySet('{F7}', 'Printer')
HotKeySet('{F9}', 'AllThingsZ')
HotKeySet('{F10}', 'Bitlocker')
HotKeySet('{F11}', 'Chrome')

Thank you again for any assistance provided. I will provide any information that is needed as quickly as I can.
I have attempted to add like a "Terminate" like below:
Func Terminate()
Exit
;EndSwitch
EndFunc ;==>Terminate
But when I attempt to run it, it does not work
