The bullet is not a *character* per se in emacs.

So you cannot do that.

The left quote (back tic) is used to trigger math symbol selection. You 
cannot easily change that, but you can remap a key as you did for M-9 and 
that will allow you to enter the selection menus. But you cannot use that 
character (M-9) to change levels. You can customize 
`cdlatex-math-symbol-prefix' to set a symbol for that purpose.

Elisp is not needed.

You need to use the customize interface. See

 	(info "(emacs) Customization Groups")

Briefly, type

M-x customize RET

Then type `cdlatex-math' in the search box and click `search'.

Then click on the mark left of Cdlatex Math Symbol Prefix, delete the '`' 
and type in the character you want to traverse levels in the math symbo 
menus. Then change the state. `Save for Future Sessions' will modify your 
.emacs for you.

It works fine for me. Be sure you have org-cdlatex-mode enabled and that 
you really are in a suitable environment. If you see messages like

 	if: No open environment at point.
or
 	if: No item defined for abc environment.

in the *Messages* buffer, you have erred.

HTH,
