Manual    --    search online help system

? key
?? key

These operators are used to search the online help system for information matching a keyword (introduced in CoCoA 4.2).

The commands have the form ?key and ??key where key is a literal string without quotes. The search for the key is case insensitive and ignores blank space before or after key . Also, the semicolon usually required at the end of a line of CoCoA input is optional.

The search system is fairly simple. The searching algorithm looks through the title and keywords of each manual page. A page matches if key appears as a (case-insensitive) substring of the title/keywords.

The ?? form prints the list of all matches. The ? form prints the page matching exactly if there is one, otherwise it prints the list of all matches.
