Nice list I didn't know before.

Thanks for the explanation.

It's not about remapping. I'm writing a vimscript in lua. In a function I need
the position of the opening and closing bracket. So in vim I would execute »%«
twice. Than I have both positions. If there would be functions for the basic
comands I just would execute the corresponding function. But apparently this
is not the case.

So I rephrase my question. How to access basic vim commands (here: %) from
inside lua? How to access an arbitrary vim function from inside lua?

vim 7.3 compiled with lua interpreter
