Thanks. So

1. If I clicked somewhere inside the surface or volume to select a
hole, how can this hole be displayed. I mean I just clicked and then typed
"q" without doing anything else.

2. If I clicked somewhere inside the surface or volume to select a hole,
how can this hole be created interactively using GUI?
