Is there a way to "convert selections"?

Thank you. But the solution I'm looking for would allow me to select a face then immediately convert that selection to just the "edges" of that face. So that I could (for instance) add fillets.
The "Types" tab in the Browser seems to only work globally. It doesn't actively change the selection type, of an already selected surface/curve/face etc. Again, I'm referencing the selection options in Cinema 4D.
