I voted caps lock, but:
just got the idea here lately to "swap" Ctrl & Caps Lock keys (in some thread where they were talking about Wordstar
amongst others ..)
I personally have disabled Apps (context menu) key, (well now it's Ctrl as well, courtesy AHK) -
cause I keep hitting it by mistake when using Ctrl+__ combinations. (Bad [lefthanded] keyboard user!)
This poll is to find out what keys might be good to use for shortcuts in small/quick scripts.
I think right windows key would be a good choice - I never use it - not even accidentally
Scoll Key - didn't even know it - anyone know what its called on a german keyboard .. ahh, "Rollen" I guess, I've never used it.
"English" Laptop (Old IBM thinkpad) has only one key Num Lck/Scrl Lck (works with shift i guess)
Dug out an english speaking keyboard - has "Turbo" but dont think theres an equivalent on the deutsch one
EDIT: changed vote to "other windows key"
