gEDA-user: what does holding ctrl mean while drawing lines?

[Ben Jackson]

I noticed EnforceLineDRC bugs out if control is held, so I figured it
would let me join rogue vias and so on.  Instead, holding control seems
to prevent the line from being displayed as I move the mouse, and when I
ultimately click I get one segment at an arbitrary angle.

What's the deal?
