To be honest I'm not sure or what I want is possible but it would be very nice if this can be done.
I changed the behavior of the Capslock to act like a Ctrl key. Now it's just an Ctrl key only positioned at an easier to reach place, which is great, but…
It would even be nicer if I could press the Capslock key followed by a second key press. I mean for example: Capslock(ctrl) → V instead of the normal Capslock(ctrl) + V.
I guess what I'm looking for is a somewhat similar behavior as the G(go) combinations in Vim or Gmail. Does anyone have an idea how this can be accomplished?
