Multiple monitors different res. Is there a quick switch

Okay, here is what I have. I have a 4870 with two displays. One display is 1680x 1050. The other display is an old ass crt bigscreen. I can clone the displays but it makes my 1680 x 1050 the tv's resolution. What I want is my monitor to be native and the tv to be native. I realize I cant do that by cloning them. What I am wondering is there an option that I can assign hot keys to, or is there a hot key combo that lets me switch between monitors. I dont need them both to be on at the same time. I would like to game on my computer monitor and watch movies on the tv? I know on laptops you can pick and switch which display fcn f4. Is there anything like that on the desktop that is quick?
