If you’re a dual / multiple monitor user, you’re probably bummed by the fact that Windows 7′s Aero Snap feature treats all of your monitors as one big desktop. I.e., with your mouse, you can only “snap” a window to the right side of the right-most screen, and to the left side of the left-most screen.
The good news is that you can get around this with keyboard shortcuts. Push Windows Key + Left or Right Arrow to “snap” a window the right or left side of the active monitor (the monitor the window is currently on). Continuing to press the Windows Key + An Arrow Key will keep snapping the window to the sides of your other monitors.
Try it out! It’s not as nice as using the mouse, but it’s better than nothing.
