FreeSnap

Ever try to size a window so it just touches the edge of the screen? It’s tedious (at least for me).

FreeSnap allows you to instantly resize any window edge to the corresponding screen edge. Want that window to touch the right edge of the screen? Press and hold the left “Windows Key” (see illustration below) and press the right arrow. It’s just that simple. The number-pad keys work as well, regardless of the NumLock state.
