Autohotkey Hotkey Pass Through

An excellent explanation (how the H are you supposed to know this without going through the documentation with a fine toothed comb? Really, the annoying 71 hotkeys received in the last 1152 ms should tell you what to do!!) by the master Johnny - of KDE drag fame..

^a::
    IfWinActive, whatever
    { 
         Send ^a
    }
    else 
    {
         Do something else
    }

Will not work. Solution, add a $ before the ^a::

That's all you have to do.
