UI: easier selection?

In a video tutorial (za06b_andy.avi) Andy models an eye as a first step. And what I see is that he select on a sphere complete rings with only one click - how does it work?

You can select separate meshes easily in the editmode if you first select a vert of that mesh and then hit ctrl-l (Select\Linked Vertices). That may be the method that Andy used.

Alt-RMB (RightMouseButton)
