In the command interpreter <m-h> (meta-h) will give you help on the current symbol before the cursor. This will be a short description of the function or variable, how to use it and what its arguments are. A listing of all such help strings appears at the end of this document. <m-s> will synthesize and say the same information, but this extra function is really just for show.
The lisp function manual will send the appropriate command to an
already running Netscape browser process. If nil is given as an
argument the browser will be directed to the tables of contents of the
manual. If a non-nil value is given it is assumed to be a section title
and that section is searched and if found displayed. For example
festival> (manual "Accessing an utterance")
Another related function is manual-sym which given a symbol will
check its documentation string for a cross reference to a manual
section and request Netscape to display it. This function is
bound to <m-m> and will display the appropriate section for
the given symbol.
Note also that the <TAB> key can be used to find out the name
of commands available as can the function Help (remember the
parentheses).
