Working on starter tutorials, problem w/ osnaps

Tutorials specify using osnaps that I don’t seem to have: on curve, on surface, between…
is there a way to get an increased number of object snaps? I seem to only have 12.

With your mouse pointer over the Osnap panel, press and hold the Control key to see them.
Are you sure the tutorial does not explicitly mention using that key?

well THAT’s interesting. One of the ones I was looking for are in there but not a few of the others. Is there another layer as well?

cannot seem to find most of these snaps…

We used to call them “one shots”
Maybe that tutorial doesn’t perfectly line up with the version of Rhino you’re running.

Gotcha. thanks.
