    Let users use the other mouse button to switch
    
    As users can have different primary mouse buttons (left vs right) it
    might happen, that a user with a different
    preference wants to switch. Currently they need
    to use the mouse button, that the current
    user prefers.
    
    This change enables users to use either the left or right button.
