This ticket is already assigned to @wmayer but nevertheless it would be nice to get some traction on it. If anybody has spare time and motivation.
Having a command (perhaps in the Tools-Section ?) which displays in a two cloumn list command and currently assigned keyboard shortcut. Maybe with possiblity to copy the list to the clipboard for inserting in Calc or Writer and then print it.
trimble Sketchup for example has a small ruby script that reads out this informations and writes the two column list in a HTML-File. This would be acceptable/conveniant too.
