Based on my previous post about getting my Logitech R800 presenting tool working with Keynote using Karabiner, I’ve now spent some time extending my private.xml to add support for QuickTime Player also. It now supports (inside QuickTime Player): Left: Rewind the video at various speeds. Right: Fast-forward the video at various speeds. “Start presentation”: Go into fullscreen. “Blank presentation”: Pause/play presentation. This is very useful when giving a “live” demo from a QuickTime video, as you can pause/play/rewind etc.
