I MAY be able to make something where the window does not need to be up.... i gota freshen up on my C skills.
EDIT:
sorry Pukka wow ignores key strokes sent while not maximized, so i have no way of making this work while minimized for now, without using functions outside the game. Also if you wanted to do it while you are browsing the internet you could use a RADAR if you don't mind hacking.
i said "tend" to spawn during that time period
