Macro to change the WoW windowed mode size?

[Stormrake]

Is there a macro that can let you change from fullscreen mode to a set windowed mode size. Right now I'm using the macro /run local a = "gxWindow"; SetCVar(a, 1-GetCVar(a)); SetCVar("gxMaximize", 0); RestartGx()
and manually changing the window size so I can watch movies while I fish in-game. Is there a macro that lets you do this or do I have to do this everytime?
