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.
You can start and stop FreeSnap by using the menu items. The only indication that FreeSnap has started is the brief banner that appears when you start it. There is no tray icon (heck, you probably have about 20 of those if you’re like me). The installation automatically places a shortcut to FreeSnap in the Startup folder. You can delete the shortcut if you don’t want FreeSnap to start automatically.
All options are set in the FreeSnap.cfg file located in the installation folder. Edit with notepad and then restart FreeSnap.
