Parent Topic: Commands

KEY

The KEY command is used to perform a keyword search of all the help topics on-line with a provided keyword predicate. The first 100 help topics that match the keyword predicate are displayed and any one can be selected at the ``Enter topic name or <RETURN> for more:'' prompt. Once a topic has been selected from the matching list, the user is placed in the normal help browser.

 KEY keyword [[AND,OR] keyword]...

The keyword predicate is a series of keywords, each with an optional logical operation. For instance ``vector OR image'' would list all topics with the vector or the image keywords, while ``vector AND image'' would list all topics with both vector and image keywords. The only possible operations are ``AND'' and ``OR'', but the default operation is ``OR'' if none is provided. Thus, ``vector line polygon'' is the same as ``vector OR line OR polygon''.

Keyword searches are case insensitive and will match any subset of the keyword stored for a topic. Therefore ``vector'' would find a topic with ``vectors'' or ``eigenvector''.

Example:

 KEY rasterize
 KEY vector AND export
