Executing function on keypress, but send this key "normally" to OS

[misioooo]

Hi!

I want to do something like:

#include <ScreenCapture.au3>
#include <Misc.au3>

Local $hDLL = DllOpen("user32.dll")
Global $running = 1

Func Quit()
    $running = 0
EndFunc

HotKeySet("{ESC}","Quit")

MsgBox(0, "Running screen-capper!", "All fine captain!", 5)

While $running
    If _IsPressed("0D", $hDLL) Then
        Sleep(800)
        _ScreenCapture_Capture(@MyDocumentsDir & "\Tutorial_screens\Tutorial_Image_" & @MON & "_" & @MDAY & "_" & @HOUR & @MIN & @SEC & ".jpg")
        While _IsPressed("0D", $hDLL)
            Sleep(250)
        WEnd
    EndIf
WEnd
DllClose($hDLL)
exit 0 

It works as i want it to work (takes a screenshot whenever i press enter key. But maybe is there some better/less resource hungry approach to this? It should take a screenshot when i press enter, but mentioned Enter must also work "normally". I tried registering it as a hotkey, but then it didnt worked "normaly".

And you may ask "Why Enter key?". Well, i want to do some tutorials with pictures and after some analysis above method will make my work much more natural and pleasurable.

Hi,

You can use the >HotKey UDF and assign a hotkey with the flag $HK_FLAG_NOBLOCKHOTKEY.
