If you are working on a relatively slow computer system you might want to try the syntonly package. This makes / skim through your document only checking for proper syntax and usage of the commands, but not producing any printed pages. As / runs quite a bit faster under those conditions, for early error-checking runs of a document this can save you valuable time. The syntonly package is a standard / package so you should find it already on your system; to use it, write
\usepackage{syntonly}
\syntaxonly
When you want to produce pages, comment out the second line by adding a
percent character:
%\syntaxonly
