I think there's a function where you can select a vert, and then press keys and be able to select neighboring verts instead? What is it called and how do I do it? I've looked in the Maya Library but didn't see anything about it. I know Xumi's got "walk selection" or something like that, but is that the only way I can do it?

There are selection tools in the bottom of the "Edit NURBS" and "Edit Polygon" menus for growing, shrinking, and converting selections. It sounds like you are looking for grow selection and select selection boundary.

Actually, it's more like if I select a vert, I want to be able to press something like the arrow buttons to jump to the vert north/south/east/west of it, depending on the arrow I press. Anything like that?

You're talking about pick walking (at least that's what I think it's called). Anyway, I don't think Maya has built in functionality to do this on sub divisions or polygons, but you can do it on NURBS surfaces, maybe that's where you saw it. Someone may have written a script to do it on polygons. You could always work with a NURBS surface and set up it's surface parameterization to make it look like a polygonal surface, and then convert it to polygons later.

Hey, thanks for the info.

Man, that's too convoluted. I wonder why no one's written a mel for it working on polygons and sub'D?? Maybe that should be my first mel project?

I think they probably didn't implement pick walking on polygonal or Subdivision surfaces beacuse unlike NURBS they can have completely arbitrary topologies. A Nurbs surface is regular and uniform so pick walking is a useful tool. for plygons you can have any number of vertecies surrounding a single vertex, so the problem becomes how do you intelligently decide which vertex to move to when the user presses the up arrow? There could be several vertecies "up" the mesh from the currently selected vertex. You couldn't accurately predict what vertex the user wanted and you'd have a useless tool, that would appear to be buggy to every day users. They probably didn't think anyone would find it useful.

Xumi has Pickwalk for Polygons
