    main: Allow finer-grained control on volume
    
    When adjusting volume using the keyboard, I often find that raising or
    lowering the volume level by 8% is too drastic a change, and I can't
    seem to hit a "comfortable" volume unless I reach for the mouse.
    
    We now bind the Shift-UpArrow and Shift-DownArrow keys to a
    volume adjustment of +2% and -2% (respectively), in the spirit of the
    fine-grained seek controls (Shift-LeftArrow and Shift-RightArrow).
