LyX ⇒ add characters to autocomplete

[sergdkv]

I am using LyX to write programs.
And I use LyX NOWEB document class.

This is work very good to python, cpp, bash and others languages.

I have a question about autocomplete LyX function.

I want to add some strings (function names, variable names etc) to autocomplete list.

And LyX uses character _ as word delimiter.
I want to make '_' character part of word (I use _ in function names).

May be there is the way to customize it?

Sorry for my english. Russian is my nature language.
