Maya Modeling :: How To Select Isoparm

Here is what I've tried so far in creating the pupil of the eyeball:

1. Right click - select isoparm - attempt to select.
2. Right click - select Surface Point - attempt to select.
3. Left clicking
4. Holding shift (and other keys) - attempt to select
5. Right clicking
6. Middle clicking
7. Marqueeing

When I right click - select surface point, I get something that looks like a selection, but it also has an isoparm dotted line.... when I attempt to DETACH I get an error.
