Bind commands to key-up and key-down in AutoHotkey

You could compile your .ahk scripts as .exe. Then have

Pause::C:\fun1.exe    
Pause Up::C:\fun2.exe

More info on .akh to .exe: autohotkey- ahk2exe

You can accomplish the desired functionality with this code:

pause::
    fun1()
    keyWait, pause
    fun2()
return

If you are dealing with subroutines instead, use this:

pause::
    gosub, sub1
    keyWait, pause
    gosub, sub2
return
