Map Win-Key To Main Menu
From Knowledge76
Ever miss being able to open your main menu with the windows key? This is an especially useful feature for laptops, so you don't have to use the track-pad to navigate your menus. Really easy, too.
Open your "System" menu, "Preferences", and then "Keyboard".
In the "Keyboard Preferences" window, open the "Layout Options" tab.
Click "Alt/Win Key Behavior." Select the "Add the standard behavior to Menu key." radio button.
Close that window, and go back to "System" -> "Preferences" -> "Keyboard Shortcuts."
Under Desktop, you should have "Show the panel menu" set to Alt+F1. Click it. Now hit the windows key and close that window.
Now test it out, win-key to open the Applications menu and Esc to close it.
