I've been on the Access train since v97, as well, and being retired for the past eleven years, spend 8-10 hours a day on this and a bunch of other Access sites, and I, too, have never heard of a Control named Panel! If that is the correct name, I'm guessing that it's from another development program, not MS Access.
The only thing that comes close is the Option Group Control, where you have any number of Controls (Checkboxes, Radio Buttons, etc.) within a 'frame,' if you will. They can be moved as a unit, but
- The Controls have to all be the same type, i.e. all Checkboxes, all Radio Buttons, etc.
- Only one of the Controls can be selected at any given point time
