[AUCTeX] autocomplete only for Latex commands/keywords?

[Jannis]

Hi Auctex users,


is there any way to activate aome sort of autocompletion feature for all 
Latex commands but not for the normal text?

There seems to be some sort of autocompletion when I hit

C-c C-m

but it only seems to offer very limited (e.g. \includefigure is not 
offered) and it will not give any environment suggestions when I type 
\begin{...

Predictive mode seems to quiet comfortable, but is there a way to switch 
it off for normal text?


Cheers
Jannis
