    schemas: Add a way to turn off "PC-style" right-click
    
    On Macs, there's no physical touchpad buttons, and right clicks are
    performed through 2-finger clicks.
    
    On Lenovos (and many other PCs), specific areas of the device are set
    aside to act as buttons.
    
    The default configuration for those is to leave it as is the default for
    that specific hardware, but allows to remove button areas on PC laptops.
    
    See equivalent, old-style work-around:
