For MacOS.<p>Oh nice. Ages ago and for several years that was my default setting on <a href="http://www.enlightenment.org/" rel="nofollow">http://www.enlightenment.org/</a> window manager and I loved it. Happy to try it on MacOS, too. My current solution is setting a hot corner to show all windows, then click on the one I'm looking for. That requires no keyboard.
