If you have a \begin{verbatim} that appears to overrun its boundaries, " use %stopzone. " " 2. Run-on equations ($..$ and $$..$$, particularly) can also be stopped " by suitable use of %stopzone. " " 3. If you have a slow computer, you may wish to modify " " syn sync maxlines=200 " syn sync minlines=50 " " to values that are more to your liking. " " 4. There is no match-syncing for $...$ and $$...$$; hence large " equation blocks constructed that way may exhibit syncing problems. " (there's no difference between begin/end patterns) " " 5. If you have the variable "g:tex_no_error" defined then none of the " lexical error-checking will be done. " " ie. let g:tex_no_error=1 " " 6.
