Thread:Talk:Semantic Maps/Special:MapEditor - Delete single points in a line/polygon?

Hello. I am trying to change the points of a line in Special:MapEditor (in Semantic Maps 2.0). Adding a point between two existing points works fine, but I haven't figured out the way to delete a single point (pressing the del or backspace key does not work). It seems I can only delete an entire line. Is there a way to do this?

Is there a manual / documentation / tutorial for the new MapEditor functions? Thank you in advance and thumbs up for the great work!
