Thank you both for such a quick reply. However, neither option worked. What I "see" as a problem is that no key has been assigned to "Command I' and I was unable to search for it by ether using the command symbol or typed out.

Might there be another approach too this?

Obviously, pressing the command key and the letter I will continue to work, but the keyboard key on the Protoarrc keyboardis directly above the backspace key (and I just triggeres it again) is also a "command I" action and THAT is where and when "all H*** breaks loose.

Cor-el, I did find Page Info on the page you identified but I'm very unsure of what to do with it, or where to do it etc. I just had to re-type this because I hit the darn cmd-I key again. I've just got to find a solution for this!
