13 " 2. Run-on equations ($..$ and $$..$$, particularly) can also be stopped
14 " by suitable use of %stopzone.
16 " 3. If you have a slow computer, you may wish to modify
18 " syn sync maxlines=200
19 " syn sync minlines=50
21 " to values that are more to your liking.
23 " 4. There is no match-syncing for $...$ and $$...$$; hence large
24 " equation blocks constructed that way may exhibit syncing problems.
25 " (there's no difference between begin/end patterns)
27 " 5. If you have the variable "g:tex_no_error" defined then none of the
28 " lexical error-checking will be done.
