Double click to terminate Grease Pencil predefined strokes, ie, line, arc, circle, etc

Currently terminating a draw operation in Grease Pencil using the five stroke tools (line, polyline, arc, curve, box and circle) requires the user to hit the ENTER key to signal completion.

IMO, this is awkward. Especially for right-handers, as their left hand needs to traverse the entire width of the keyboard to hit the ENTER key.

I propose that a double click on one of the terminating nodes be an additional option to terminate the draw operation. The ENTER key can stay (why not?) but adding the double click operation spares the user from an awkward reach.
