Q & W are very important, press Q when something from buildings tab is ready, see what it does. W does the same for something in armory tab.

Use spacebar to immediately move the view to wherever an "event" happens, such as unit lost.

H is obviously useful for jumping view to your primary MCV.

I don't use this one much- Ctrl+F1 will mark a position, if you press F1 wherever you set Ctrl+F1, the view jumps to that place. Works also for F2, F3, and F4.

And remeber, ALWAYS move your camera using right click. Also set scroll speed to max.
