Run full screen apps in a window

Does anyone have any ideas about how I could make a full screen application like Quake3 run inside a window? (smaller than the screen!). I don’t HAVE to use applescript to do it, but it seemed like the obvious option.

probably depends on if there is a keystroke for running it in a window. I don’t have Quake3 so i don’t know if it supports applescript, but you should be able to make a script to press the keys… run searches for applescript key press and special characters, cause you probably have to hit apple-command-shift something. Sorry can’t help more fairly new to AS myself.

thankyou! I’ll look into it.
