My issue is deceivingly simple.
I have this combination in my .ahk file:
Capslock::Shift
This works. If I hold down Capslock, it doesn't activate, but it does whatever Shift has to do, which is exactly what I want.
Now, if I take it a step further:
Capslock::^+
It should work in paper, but it sends automatically Ctrl+Shift+= or Ctrl+Shift+=, instead of letting me use Capslock as Ctrl+Shift.
Any thoughts on how to bind two modifier keys into one single key?
