Well, this was new to me at least.
I use to click one letter at a time, wait for it to move, then click the next. If I needed to move a letter from the top to the bottom... it took two slow clicks.
But did you know that you can click multiple letters in rapid succession and they will all move together? For example, to go to the Edgeville Canoe Station, click D once, K twice and R twice, as fast as you can. All the wheels will move at once.
OK, maybe it's not as exciting as discovering a new colony of gorillas, but it does save some time.
