I've used Windows Office for a long time, and one feature which I love is the ability to zoom in and out with a mouse scroll wheel while holding the control key. When I first started using MS Office on a Mac, I found that this only zooms into the bit map image of what is on the screen (this is system wide in OS X), which is not at all what I want (fonts look jagged). Well tonight, while playing with Office 2008 (which I just installed) I tried this with control+option instead of just control, and, what do you know, the zoom in/out works. Fonts scale beautifully, just like I'm used to. I'm so happy 
Btw, this works in Office 2004 also.
