Consume keystroke in autohotkey (don't let it propagate to other apps)

Question

I have a problem have a keystorke set in autohotkey, but teh problem is that one program running on background consumes that keystroke and autohotkey action doenn't trigger at all. I need autohotkey to consume that keystorke first and don't let it get away so other application doesn't notice it ever happened.

Edit:

!t::
send {up}
return

This works just fine without background program running (Taskbar Eliminator)

Answer 1

Try putting a '$' in front of your hotkey. Like this:

$!t::
send {up}
return

Otherwise to make your script be the last to register the hotkey, you can make it restart after a few seconds like this:

Sleep, 5000 ; 5 secs
Reload
