How is the blinking caret emulated in Etherpad? (See a live version at ietherpad.com) The way I would do it, is to create a div and position it absolutely where the caret should be. Then, display and remove it in regular intervals. However they seem to do it differently.
The text of a row is in
<div id="magicdomid2" class="">...</div>
I can't see anything changing around the div. How is it done?
