Ok. There are some new updates.
It should be related with hardware.
Now I try to enable CF in another laptop- Dell Inspiron 9300. Everything works well.
The problem only occurs in my new laptop - Lenovo T61p.
I'll investigate more to find out what's happening in the Thinkpad.

I'm sure no other shortcuts besides compiz's own definitions work.
I also try your way. Unfortunately it proves my conclusion too. Compiz eats up the alt. When I press "Alt+e", nothing happens. When I disable compiz and try it again, I can get "^[e" while pressing "Alt+e".

Compiz-Fusion has lots of keybindings; it is supposed to intercept all the
keys that it is supposed to listen to.

Are you sure that compiz is intercepting _all_ keys with alt?

A basic test to see this would be to open a terminal, run cat, then type
away, holding alt (under compiz of course).

You should then see nothing. If the keys are not intercepted, they look
like ^[e for M-e..
