Q: how to clean or trouble shoot powerbook G4 keys

Wow!

What a great reply to my question, and the links were just phenomenal. . .  I never use google to search for anything, but the stuff that you sent me, astounded me.  The ifixit link is now om my favorites tool bar. 

     I fix things for a living, and this site will now help me to be a lot more effective in my endeavors.

I am not a geek, but with the instructions on ifixit, I could become one quite easily.

I removed a few key caps and tested my G4 out, and the keys did not work then either.  I am assuming that I may have to replace the keyboard, or that there is a wire loose, or possibly a software issue. . . 

     ifixit will help me exponentially in that matter.

I thank you so much for opening my eyes, and heading me in the right direction.  I am truly grateful for your help.

     I just your reply to my question this morning, and I have not yet had a chance to go through it and explore it fully, but I will, just as soon as I get home from the work I need to get done. . .

Thanks again for such a useful answer to my problems. . .
