when using the keyboard, if you need to move the cursor over you can use that button to do so...just put you finger directly over the blue dot and flick left, or right - you should see your cursor input reference move in the direction you flicked. You can flick any number of times to get were you need to put the cursor - GREAT TOOL!

It works like a ThinkPad button. I use it all the time.

This button allows you to move the text caret to delete letters and such, from a browser URL for example. It is really useful.
