Great tip!
Cheers
The only downside of it is that if you want to chat to someone in steam it keeps reassigning the keys so I use this to disable it:
; f11 suspends script
; reenable long beep
; suspend short beep
f11::
Suspend
if ( A_IsSuspended )
{
SoundBeep
}
if ( !A_IsSuspended )
{
SoundBeep, 523,850
}
There might be another way but it's all a bit complicated for me haha.

(I also use it for sprint on sniper,as n is quite far away so e is easier) Give it a go in single player to test it, save the game when you have Guards and Cons on the field.
