Bridge/extrude/join vertices in a ring I have a ring of vertices, and I would like to connect them with another edge together quickly. 
I tried bridging 4 vertices together, but that took too long and made faces. Extruding with 'E' would also take too long.
I couldn't find any way to do it before, but here is an example of what I would like to do: https://youtu.be/ENmN5PVMcQQ?t=1m41s
How do I do this?
I tried the bridge loop method, but it does all of the vertices at once, and it creates triangles, which I do not want either.
If you want to do this automatically, you can use Bridge Edge Loops by selecting the rings, pressing Spacebar and typing "Bridge Edge Loops":



If you prefer a semi-automatic way, make sure you have F2 addon enabled in User Preferences Ctr+Alt+U > Addons.
Then select 2 vertices using F and continue filling the loop by moving your cursor in the direction you want to create faces and pressing the F (can be pressed repeatedly):
