Don't be afraid to look at the source code to see what the components do.  You'll get more knowledge that way.

So that I could allow a user to select a vertex and then if they choose to delete it, I can just pull out a reference to it in the code from the modify feature. I suppose this could also just be a deleteSeletectedVertex function on the modifyFeature control too.
