This question already has an answer here:
Windows 7 has a nice new feature for moving around windows.
The one that I am particularly interested in is: Windows Key + Left/Right : Move the window to the left or right of the screen, or over to a second monitor.
But, Windows Key + Up: Maximize the current window and Windows Key + Down: Restore or minimize the current window. are also quite useful.
Is there anyway that I can get this functionality in OS? Preferably replacing the windows key with Command Key.
