Interesting windows application to automate some repetitive tasks, you can also create hotkeys to provide, customized, more friendly keyboard shortcuts, like the example:
LAlt & WheelDown::AltTab
LAlt & WheelUp::ShiftAltTab
(This is not Tcl of course)
such script lets you switch between open application by pressing the Left-ALT key and the mouse wheel, instead of the awkward ALT-TAB combination.
