Alt-Tab Thingy is an Alt-Tab replacement utility and much more.
Alt-Tab Thingy is for Windows XP, Vista & 7 only.
If you are not familiar with the Alt-Tab task switcher in Windows, it’s a keyboard short-cut (hot-key) to enable fast switching between applications/windows. This feature has been in Windows since Windows 3.0 and is largely unchanged since Windows ’95! Alt-Tab Thingy is a replacement to add brand new features to help you switch tasks faster and more efficiently than ever before!
