JumpKeys for Windows

The description of JumpKeys - Play With New Friends

A utility that uses hot keys for selecting (switching between) windows, minimizing, maximizing, and making windows Always On Top. JumpKeys gives you instant control over your desktop windows. Quickly tag up to 9 of your most frequently used windows, to be selected using the numbers on the main keyboard. By default, tagged windows can be selected using the Alt key (Alt+1, Alt+2, and so on). The number 0 always selects the window that previously had the focus (Alt+0). If you prefer, you can select tagged windows using the Ctrl key, Shift key, Windows key, or even with the numbers alone. Tagged windows are identified based on full or partial title. Repeating the same window selection hot key (e.g. Alt+1) will cycle through multiple instances of a tagged window. Also, you can assign a hot key to minimize windows, and assign a hot key to alternately maximize/restore the current window.
