Are you tired of dragging your cursor to every point of your screen just to resize windows? Window Wrangler lets you perform just the same actions, except by using your keyboard. Those of you that love using keyboard shortcuts, will enjoy this program.
Using your up, down, right and left directional arrows and a combination of other keys you can move between windows, resize them and place them anywhere on your screen. All in all, it almost makes your own mouse useless. The catch is that you'll have to go straight to preferences to learn what the keyboard shortcuts are first. You can also adjust both movement and size speed by way of sliders, however I encourage you to give Window Wrangler a try before hand. It might be that the preset speed is fine for you.
Window Wrangler is fairly easy to get working with however I would have liked to see some sort of tutorial or guide just to get new users comfortable with the program, especially those less familiar with keyboard shortcuts.
If you enjoy working with keyboard shortcuts, you'll like using Window Wrangler to resize windows.
