I'm a big fan of keyboard launcher utilities like Quicksilver and LaunchBar, so I was intrigued by what might be thought of as the next logical step. MercuryMover
is a little Preference Pane utility that allows you to move or resize on-screen windows without using your mouse. The idea is that you hit a user definable key combo and a bezel will pop up which lets you to move or resize the active window by a set number of pixels (or to the edge of the screen).
MercuryMover is $20 and a demo
is available from Helium Foot Software.
