macro script guide

i wan a button to be hold when i click the macro button and the button to be released when i release the macro button . for example , i hold G and right click will also be held and when i release the G button the Right click will be released too

If its for autohotkey just put this in the script after "Loop">
if not GetKeyState("Buttonyouwant","P")

what if i use DllCall("Sleep","UInt",16) or DllCall("kernel32.dll\Sleep", "UInt", 16) ?
