I'd like to use Capslock as a modifier key. To create this without risk of clashing with other key combinations, I'd like to use Ctrl+Shift+Alt, i.e. Capslock+u would become Ctrl+Shift+Alt+u. Capslock+p would become Ctrl+Shift+Alt+u.
I would like to only configure the modifier key mapping in autohotkey, not each combination individually.
I've tried:
Capslock::^!+
and
Capslock::Send ^+{Shift}
But the first is recognized as Ctrl+Shift+PlusSign and the second doesn't seem to work at all.
