 Vim understands three types of syntax items:
 
-1. Keyword.
+1. Keyword
    It can only contain keyword characters, according to the 'iskeyword'
    option.  It cannot contain other syntax items.  It will only match with a
    complete word (there are no keyword characters before or after the match).
    The keyword "if" would match in "if(a=b)", but not in "ifdef x", because
    "(" is not a keyword character and "d" is.
 
-2. Match.
+2. Match
    This is a match with a single regexp pattern.
 
-3. Region.
+3. Region
    This starts at a match of the "start" regexp pattern and ends with a match
    with the "end" regexp pattern.  Any other text can appear in between.  A
    "skip" regexp pattern can be used to avoid matching the "end" pattern.
