I want to: Connect newly created vertex to existing selected vertex, forming a new edge. I read the included tutorial; the closest I found was drawing lines as part of a spline. Still, it doesn't seem to cover creating/connecting edges. BTW, it's very easy to do the above in Blender

All you have to do is select both vertices, assuming you're working with a poly, not a mesh (which you should be doing, anyway), right click and select connect.

You are right; my mistake was that I was in Edit Mesh mode the entire time.

It seems if I select an isolated vertex in space and a vertex in the mesh, I cannot connect them to form an edge.

Currently, I add new vertex as follows:
select an edge AB, insert vertex C in between AB.
Drag C to desired position.
Select vertex A,B, and connect them again to form edge.

Probably better way exists?
