This is a good video demonstrating starting and stopping when the saddle is too high to comfortably put a food on the ground. I raised mine recently and I'm trying to get used to doing it this way; I find stopping awkward, but starting is pretty easy. You stand over the top tube with the pedals horizontal, then when you step onto the forward pedal you propel the bike forward while lifting yourself up (as if you were going to pedal standing) and then settle back onto the saddle while you're moving.
