Michael,

OK, thanks for that. I'll mark it as "unused". Too bad about not having something like it working though. That's one of the few things in MoI that sometimes drives me almost to distraction...trying to select a surface in a sea of edges. I usually have to zoom in to make the edges all retreat far enough away so that I can select the surface I'm after. Being able to constrain the selection would be nice. I guess we'll see a solution to that in some form in V3. The "Types" thing sounds a little unwieldy though...maybe a modifier like the 'Ctrl' key modifier to force 'deselection' mode.
