#1222 auto-complete for indexing

[Florian]

I was wondering whether it would be feasible to add auto-completion for creating indices.

I'd image it should be possible to reuse the mechanism for auto-completion of cite-keys and get it to read the .idx (or .idn if that's easier) files...?

As indices can get very long and one doesn't always remember how a particular entry starts, it would be a huge help if the auto-completion would search all parts of the existing index-entries (perhaps eligible as an option in Preferences)
E.g.:

Typing "\index{TeX…" in texstudio would then also list entries like:

\index{CTAN (Comprehensive TEX Archive Network)}
\index{LaTeX@\LaTeX}
\index{macro languages!LaTeX@\LaTeX}

perhaps even with highlighting the matching letters.

An ideal solution for me would also be aware of multiple indices as offered by the index-package.

Thank you for considering!

Best regards,
Florian.
