The key is to watch the pivot foot. This is well defined and several in this thread have discussed this.

The hardest part I see is when the dribble is picked up. I have seen players use a high dribble take a couple of steps without holding the ball, then jump, grab the ball, take a hop, land on both feet (or close enough), then shoot. This is usually going through players in the lane. It looks a lot like a travel, but it isn't. I had a coach go over this with me once with his hotshot player and I had to agree that it was not a travel. However, most officials would call it traveling.
