The playback controls on the large 69mm (2.7-inch) fold-out screen double as backup start/stop and zoom controls, as well as a nifty one-touch button that adjusts for backlit subjects.
These duplicate controls not only give lefties an easier ride, but also allow you to move the Canon HF10 about with more flexibility, or hold it in straight-arm position rather than the usual elbow-bent shoulder-level position. A wrist strap complements the usual handstrap for different shooting positions.
