Hold Super - Invoke the Launcher and display the shortcuts
Hold Super, then press 1 or 2 or 3 and so on until 0 to open or focus
an application. The number corresponds to the location of the icon on the
launcher from top to bottom.
Adding Shift will open a new instance of the application if it's already
open.
Holding the key is also useful when you want to get to the Launcher but
do not want to invoke the Dash.
Super + T - Open the rubbish bin/trash can.
Alt + F1 - Put keyboard focus on the Launcher, use arrow keys to navigate,
Enter launches an application, Right arrow exposes the quicklists if an
application has them.
