add points with pencil editor

How do you add points/nodes to a line when editing with the pencil editor?
I needed to adjust the line thickness but often I ended up with a line that only has nodes at both ends.

attached an image of what i mean…

cheers

Using your “Pencil Editor” too, you need to Ctrl+Click the central line of your pencil line to add thickness nodes at other positions (than at line ends).

You are totally right!! Thanks RKriz!
I’ve been aiming the wrong place, I keep on trying to add point on the edges of the line, should have pointed my cursor to the center of the line, silly me!!
