Skip to last line if your sickened by my excuse for auto leveling.

Well basically I'm playing this rpg based in wc3 engine(the black road 2.0 to be specific), its incredibly long and had a ludicrously high level cap, which you pretty much have to reach before doing anything.

Now 99% of the characters could be told to patrol through some badguys and back to a healing well or something, to make the endless grind easier, my char however is completely useless unless casting spells, so i basically setup a controller with appropriate hotkeys setup as autofire buttons and jammed them down, yay fixed my char autocasts the spell.

I only got one problem, everyone else can do this without jamming a key down, needing to jam a key down ties up my computer, id really love to tab out and play some other games during the grinding between each quest or boss we fight.

So does anyone know a way to enter button presses into a background app, without disturbing anything else?

Basically i need something like autohotkey, but something that can be told only to enter key presses into a single program if possible.
