<ALT+F2> Keyboard Shortcut
Most Linux desktop environments set <ALT+F2> key combination as a shortcut for running apps and commands. By hitting <ALT+F2> key, you can launch executable binaries located in various “bin” folders in your Linux system as well as “.desktop” launchers. Just type your command in the input box and press <Enter> key to run it. Some of these <ALT+F2> launchers also support auto completion.
