There are some things of Lyx that I can not understand:
I am working with an article and from time to time Itransferred it to pdf in
order to have a pre-view . Suddenly one of those times that I wanted to
transfer it and I get an error of one part of the article that I have not
"touched "when I want to see the pdf and up to now Lyx never give me this
error. The error is the following;
I have an article (paper style) but in two column and something wrong is in
my "keywords" section:
" \noindent \textsf{\begin {multicols}{2}}
I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'."
what is wrong with it?** How can I make that lyx forget this mistake and
move on?
THANKS
