ClickLess allows you to change from one window to another within the same program without having to click on any of them first. The program must support the MDI (Multi Document Interface) conventions to work with ClickLess.
ClickLess works in the background monitoring your mouse movements, detecting when the mouse pointer displaces from one window to another, changing the focus and making the new window become active immediately for editing, data input, etc., without having to click on it first. The program has been tested thoroughly for months with time-critical musical software like Cakewalk Pro Audio 9, Cubase VST 24, SoundForge, Encore, and others like Microsoft Office 97, Visual Page, etc., without any noticeable or adverse effects.
