How to remap capslock key to EMACS super using Autohotkey?

Question

This site shows how using the registry. http://www.emacswiki.org/emacs/JonasOster

Answer 1

Another page on emacswiki suggests this in AutoHotKey:

#IfWinActive emacs  ; if in emacs
+Capslock::Capslock ; make shift+Caps-Lock the Caps Lock toggle
Capslock::Control   ; make Caps Lock the control button
#IfWinActive        ; end if in emacs

Answer 2

I don't know what Super does, but I mapped CapsLock to Emacs using this script:

CapsLock:: 
  ifwinactive ahk_class Emacs
    send {f16}
return

This sends f16 to emacs when emacs is active and capslock is pressed. My keyboard does not have an f16 key, that's why I chose that and in emacs I bound it to some function:

(global-set-key (kbd "<f16>") 'some-function)

Note that the AHK script does nothing with capslock when emacs is not active. I prefer that, because I consider capslock useless and I press it only accidentally, so it's OK if it does nothing then. You might want to do something else with it if the ifwinactive yields false.
