revised command topics

* Added some keywords.
* Consistently added command variants with all modifiers.
  In principle including modifiers in the topics is unnecessary -
  you can always strip the modifiers and look up the raw command.
  However, looking up a command with modifiers can speed up the process
  (compare looking up ?S<TAB> vs ?::S<TAB>
* The `@` modifier is listed only for commands without string arguments.
