Those two characters are the Japanese characters for comma (not a backtick. It shows up at the bottom of the line, not the top) and period. They're only available in the Japanese input modes. They're like the Japanese brackets about U and I. If you want a backtick, and this is a good suggestion to include in English Cacko I assume, I'd use keyhelper to bind it to fn+u or fn+i
EDIT:
Nevermind, I just re-read iamasmith's notes. Technically, backtick seems to be bound to SHIFT+ - (The same key for @, but @ is FN+ - )

I was about to reply to Andy's reply and say that shift + - resulted in =. Then I read your reply kahn and did some experimentation. Shft + Fn + - makes a `. Big relief. Don't know how one could get by in Linux/Unix without a backtick character.
I had made a cheat sheet for the 6k but they don't map across. In case you're interested as the proud new owner of a 6K, here it is
