In the Lines toolbar, we have a button for Line and a second button that has LMB Polyline and RMB Line Segments. The Line Segments button - which actually runs the poorly named Linescommand - just makes an exploded polyline.
What is missing is something I use often - multiple non-connected line segments - i.e. a repeating Line command. This is easily accomplished with
! *_Line
My suggestion here is that this should be the RMB command under the Line button as default (I put it on mine a long time ago)…
