Detect a double key press in AutoHotkey

Question

I\'d like to trigger an event in AutoHotkey when the user double \"presses\" the esc key. But let the escape keystroke go through to the app in focus if it\'s not

Answer 1

With the script above, i found out that the button i wanted to detect was being forwared to the program (i.e. the "~" prefix).

This seems to do the trick for me (i wanted to detect a double "d" press)

d::
keywait,d
keywait,d,d t0.5 ; Increase the "t" value for a longer timeout.
if errorlevel
{
    ; pretend that nothing happened and forward the single "d"
    Send d
    return
}
; A double "d" has been detected, act accordingly.
Send {Del}
return
