I think you want to auto-select the new face. I think that is best too. But I checked my fork (https://github.com/mick-p1982/mm3d) and it doesn't do that, so I will try to remember to add this. Anyway, you might want to try my fork since it's a lot better. But it's not back-compatible. Also the default hotkeys are different.

The created triangle is now auto-selected (ed31626) and the Select Vertex tool will (un)select triangles (fd1165f). The process @dvhx wrote should work now.
