[O] Latex index using makeidx

[Vikas Rawal]

I am adding index entries in an org document, to be used with makeidx latex 
package. While the usual \index commands are working without any problem, I was 
wondering if anyone knows of an existing emacs utility that would add an 
autocomplete kind of facility (on the basis of previous entries) while making 
new entries.

Sorry, this is not strictly about orgmode but about emacs. Please excuse me for 
that.
