Skrommel writes about ShiftOff: "Turns off CapsLock when Shift is pressed together with A-Z or other user defined keys." And it really does. I think most times when CapsLock is activated unintentionally it happens by accidently hitting CapsLock instead of Shift.
I therefore ask for a ShiftOff modification. When ShiftOffMod is active, Shift + Key should work as usual, CapsLock should work as usual, but CapsLock + selected Key should be equivalent to Shift + selected Key. In other words, CapsLock behaves like Shift in selected cases.
