Aviassin's EdgeSwap is a task switcher with a twist: you just move your cursor to the left edge of your desktop, select your window from a series of thumbnails, and EdgeSwap does the rest. It's portable freeware that runs in Windows 95 to 7.
Since EdgeSwap is totally portable and pretty small, too, you can stash its extracted executable file just about anywhere and run it with a click. We did, and EdgeSwap placed its icon in our system tray but gave no other indication it was working. However, we followed the program's instructions and rolled our cursor up to the left side of the desktop. EdgeSwap popped up with a dialog bar in the middle of our screen containing thumbnails of all our open windows, each highlighted momentarily. We merely had to roll our cursor away from the corner while EdgeSwap was highlighting the window we wanted, and the window popped up. To open another window, we just repeated the process. Open windows stay open, but to clear the desktop we had to select the desktop thumbnail in EdgeSwap. There are no options to set; right-clicking the system tray icon merely accesses About and Exit buttons. Part of this program's appeal is its simplicity, and a few seconds of practice was sufficient to have us flicking windows open with rapid mouse moves.
EdgeSwap is the sort of small, free app that can make a difference in your productivity. It's free and easy to install and use, so we recommend trying it yourself.
