Helium Foot Software has announced the release of a public beta version of MercuryMover 2.0, its window resizing and moving utility software for Mac OS X. It's free for the public beta; once it's released, it will cost $24.
MercuryMover enables you to move and resize windows on your Mac using only the keyboard. You can move and resize by 1, 10 or 100 pixels at a time or to the edge of the current screen. MercuryMover is aware of multiple screens.
The new 2.0 release adds one-key shortcuts, window information and an updated interface.
System requirements call for Mac OS X 10.5 or later and 2.9MB hard disk space.
