through the help of manual, i can get the following symbol's meaning now.
^ To the first non-blank character of the line.
|exclusive| motion.
\d digit: [0-9] */\d*
\+ Matches 1 or more of the preceding atom, as many as possible. {not in
Vi}
Example matches ~
^.\+$ any non-empty line
\s\+ white space of at least one character
/; E386 A very special offset is ';' followed by another search
command.
\...@! Matches with zero width if the preceding atom does NOT match at the
current position. |/zero-width| {not in Vi}
Like '(?!pattern)" in Perl.
remained question: what does "//" mean?
