Okay, ya, so I'm a WoW addict and I mix real work with blowing up horde and raiding.
Does anyone know of a hotkey to switch between Windowed mode and full-screen mode? I can't tell you how many times I have to switch to the video settings and screw with them just to switch the modes.
Please tell me there is a hotkey hidden somewhere ...
Depending on what you're looking for and why you want it windowed, try using "Windowed mode" combined with "Maximized". That will give it the appearance of being fullscreen, but also allow you to alt+tab instantly. I don't think there is a hotkey for that though.
That's what I do.
If I'm not mistaken, Alt-Enter switches between full screen and windowed (if you're running Windows anyway.)
Naah, I play at 2540 x 1280 and the graphics speed is night and day between the hardware rendered full screen mode and the windowed mode which is very "jerky".
So there really is no way to toggle the windowed checkbox with a hotkey??
