OSX #5: Alt-Tabbing in Mac (Switching between windows on Mac)
By arungupta on Dec 25, 2007
Switch between different windows of the same application: Command+~ (for example if you have multiple windows of Firefox). Shift+Command+~ moves in the reverse direction.
However if the application is minimized then it is not activated (which is bizarre)!
If you are holding the command key and hit Q then that particular application will quit, if you hit H then that application will hide (go behind all the applications?).
