Run makro while key is pressed

[WturboM]

Hello,

i am using a simple script for keeping a button pressed. Now i want to modify it but i am not sure which command i need. The Makro should run while the button is pressed, if the button is released then the makro should stop, if pressed again it should run again. A keywait or GetkeyState command would be right i think. So i can add maybe a short time, i want to say: if button RButton is pressed for 1 second then start .. and press the Numpad1 up and down every 100 ms. Here is my skript: Numpad 2 is not needed, only Numpad1 and RButton, it was just a try.

~*Numpad2::
while (GetKeyState("RButton"))
Loop 50000
{
Send {Numpad1 Down}
Sleep 10
Send {Numpad1 Up}
}
return

esc::
exitapp

i would be thankful for any help.
regards
