Dock Windows in Windows 7

There are two ways to dock windows in Windows 7:

1. Use the mouse and snap windows to the left or right side of the screen simply by dragging them up against the edge of the desktop. Using this feature makes it particularly easy to perform side-by-side comparisons of two windows.
   
2. You can also maximize a window by dragging it up against the top of the screen. Or hit Win + Left/Right Arrow on your keyboard, in lieu of mouse gestures, to dock your windows. Not only are keyboard shortcuts faster, but they also allow you to dock windows to the shared edges of screens in multimonitor setups (something you cannot do with the mouse).
   
   2a. An additional benefit of using the Windows key is that Win + Down Arrowminimizes a window.
