Have a conventional keyboard that rf was getting into. Put 3 ferrite beads on it and it seems to be working fine. I see ads for rf suppressed keyboards, any idea what their approach is?

Many manufacturers use a clamp-on ferrite bead on the keyboard line.  It's usually encapsulated and looks like a plastic knot in the line.

Another thing that also works is to ground your PC case to your station ground. It works so well for me that I could remove the ferrite beads hanging off the cords which can be a pain in the rear end. Either way ferrite and ground the case will help. Just make sure you scrape off the pain to make contact with the cases bare metal.
