However, the user was more worried about their ext. HD being trashed. The only real fix was to remove the drive or park it in some cubby hole. The same applies to a kybd. as well. You can place the kybd. using "Velcro strips" to maintain its location or rubberized mats(soft spongy mats) to help keep it from sliding around. -OR- use a kybd. shelf/drawer that can be mounted on your desk in some way. Also called a " tray" can be mounted under the desk or on top, like under the monitor or similar. One cheap and darn good fix, is to make a short leash. Using some cable, crimp on both ends a loop or eyelet electrical connection then screw down those eyelets. It basically tethers the kybd., shy of falling off desk. good luck
*NOTE* if you tether the kybd. be sure you don't screw into an electrical contact within the kybd., you can re-use a current screw hole, etc. if present. If you mount a tray, you may need to finesse it into place.

I usually have 4 to 5 keyboards at a time going. I have a large desk, but sometimes my cats want to help (theyre good with the mouse). Unfortunately they tend to knock my keyboards off the desk, and eventually the keyboard cable pulls loose and separates, leaving me with a paperweight instead of a keyboard. I'm averaging 3-4 months per keyboard at $50 each (MS ego 4000). Looking for info on any kind of pre-fab cable protection that goes around the end of the cable and fastens to the keyboard to mitigate the shock if/when a keyboard falls and is hanging by the cable. I've tried tape. It's not a perfect solution by any means.
