Consider the following piece of latex:

I would like to limit the autocomplete word list to contain only the
words on the left of the `&'.
How could this be done?
I don't mind if I have to actually specify the words rather than vim
finding them automatically.
I find the easiest way to use completion is to use "custom" and just
create a function that returns a newline-separated string of
candidate strings. The MyComplete() function below uses
getbufline() to put all the lines in the current buffer into a list,
then uses map() and matchstr() to replace each line by the word
preceding the '&'. Any non-matching lines are replaced by empty
lines. Finally, filter() gets rid of the empty lines and join()
joins the remaining lines into a string, with the lines separated by
newlines.
function! MyComplete(ArgLead, CmdLine, CursorPos)
return join(filter(map(getbufline("%", 1, "$"), "matchstr(v:val, '^\\k\\+:\\ze\\s*&')"),
"v:val!=''"), "\n")
endfunction
command! -nargs=1 -complete=custom,MyComplete MyCmd echo "<args>"
Typing ":MyCmd " followed by a <Tab> then results in the following:
:MyCmd
ONE: TWO: THREE:
:MyCmd
Modify to suit.
HTH,

Great, thanks.
