`\sCODE'
     matches any character whose syntax is CODE.  Here CODE is a
     character that represents a syntax code: thus, `w' for word
     constituent, `-' for whitespace, `(' for open parenthesis, etc.
     To represent whitespace syntax, use either `-' or a space
     character.  *Note Syntax Class Table::, for a list of syntax codes
     and the characters that stand for them.

`\SCODE'
     matches any character whose syntax is not CODE.

...

 -- Syntax class: symbol constituent
     "Symbol constituents" (designated by `_') are the extra characters
     that are used in variable and command names along with word
     constituents.  For example, the symbol constituents class is used
     in Lisp mode to indicate that certain characters may be part of
     symbol names even though they are not part of English words.
     These characters are `$&*+-_<>'.  In standard C, the only
     non-word-constituent character that is valid in symbols is
     underscore (`_').
