This might be a shameless plug, but I have created a javascript markdown editor a few months ago. I had some problems with the wmd editor (weird quirks and bugs) and generally wanted to play around with js. So, uedit[0] was born. You can use the demo page[1] to see it in action. It works in ie6+ and doesn't require any other js libraries.
List items are added automatically and you can use shortcuts for the most frequently used markdown tags such as bold, italic, code listing, images etc. It also uses it's own undo/redo manager for more granular control.
