It adds some syntax colouring to help files, apparently.

Vim helpfully :) sets the keyword matching characters (option  
iskeyword) to include any character other than "|* when you're in a  
help file. I couldn't find a way to override this behaviour; even  
putting a modeline in the help file doesn't change it.

As I find \lr awkward to type (and ctl-] is not much better, being a  
three-finger operation on a spanish keyboard), I added the following  
line to luarefvim.vim which remaps F1 to Lua help. I haven't tested it  
a lot, but it seems to work. You could use a different key, of course.  
(For a scripting language designed for text editing, vim's native  
scripting environment leaves a lot to be desired, imho.)

--- insert after the other four *map commands. This is all one line ---
map <silent> <F1> :call  
<SID>LookUp(matchstr(strpart(getline("."),matchend(strpart(getline("."), 
0,col(".")),".*\\W\\w")-1),"\\w*"))<CR>


And thanks to Luis Carvalho for the resource.
