Thanks so much for your prompt and thorough responses.
As for locking it, I actually had not thought of that. Thanks for pointing it out, but monitoring my server apps is actually important and locking the station would impede that.
Thanks for the link to toddler trap, sounds exactly like what I need! Come to think of it, I believe I even saw the original request for this and had forgotten entirely about it.
As for kid-key-lock and pro-key-lock, thanks for your links, I will try if toddlertrap doesn't suit my needs.
