Anybody came across any secret menus, buttons for GS100k or MX 5000, like some sony cams?

Or any interesting features are available using those combinations for these buttons/menus?

I don't know of any hidden functions on the Panasonic cams, but
I'm very interested in your reference to this regarding Sony units.

What hidden features can be accessed on Sony cams? Models?
Exactly what buttons should be pushed (step by step please, I'm
somewhat slow in these matters).

Do you have any web sites you could post that reference how to
access the hidden features?

Randy, I think some models of Sony, JVC have some secret menus, buttons setup. If you visit Sony 950 forum some people were discussing on those subjects.
