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

Question

I have written two functions in an AutoHotkey script: fun1() and fun2(). I now need to bind fun1() to when Pause is pressed down, and bind fun2() to when Pause is released.

As an example, I would press and hold Pause to hide all windows, and release Pause to restore all windows. (This example is not my actual objetive).

How can I do that in AutoHotkey?

Solution 1

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

Solution 2

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

Actually, compiling them is unnecessary. I already defined them as functions. My question regarded specifically to the key up/down syntax. I wasn't finding it in the manual, so I asked here. Eventually I found a couple examples online, and it's exactly what you said except there's a blank space between "pause" and "up/down".

No need to add Down since its the default trigger. Only Up must be specified

This is right answer. Because it handles long press without sending mulltiple "keyDown" events.

Wrong. Long press of Pause will send multiple "keyDown" evens, launching C:\fun1.exe multiple times.
