3. Unclip your right foot.
4. Move forward off the seat into a semi-standing position, still supported by your left leg.
5. Coast to a stop and put your right foot on the ground as you stop.

There shouldn't be any crazy jumping around with this. If you can't get unclipped you can just lean back onto the saddle and pedal a few more strokes (on a path).
