My favorite - view 2 windows side-by-side for comparison. This can be not just browser windows, but also documents, email or whatever you have open in a window.
While pressing the Windows logo key , click the Right Arrow key or the Left Arrow key and your browser will slide over to one side. Select another window (such as a Word document) and use the shortcut only with the opposite arrow.
Worthy of mention - Zoom in, zoom out. This is like the Ctrl + or Ctrl - in your browser.
Windows logo key +Plus Sign or Minus Sign
The Plus Sign key (+) zooms you in, the Minus Sign key (-) zooms you out. This lets you see small text on a webpage or to check out the pixels in a photo.
