The key [C-M-b] does not work in Emacs.

The key [C-M-b] does not work in Emacs.

[numbchild]

I found Emacs key =[Ctrl-Alt-b]= does not work, but I try its binding
command
=[backward-sexp]= can work. and it does bind to key =[Ctrl-M-b]=, and I use
=[Ctrl-h
k]= (=describe-key=) can capture =[Ctrl-Alt-b]=.

I'm curious might KDE captured this key, but I check out all KDE settings
"Shortcuts", not found. Then I tried command =xev -id <Emacs window ID>= to
capture key under X11. Here is the log:

If anyone knows solution how to solve this problem, please give me some
hints,
thanks very much.

But, C-M-b works for you, otherwise
`describe-key' wouldn't react on it, right?

What happens if you hit it in an Elisp
mode buffer?

Weird, after recently (about two or three weeks) compiling Emacs source
code frequently, `[C-M-b]` works now. weird. This problem is recorded many
days ago. I come up with it recently. So I post it here. It is my fault
without verify whether it works now. Sorry for distribution.
