Maxima Function
apropos (string)
Searches for Maxima names which have string appearing anywhere within
them. Thus, apropos (exp) returns a list of all the flags
and functions which have exp as part of their names, such as expand,
exp, and exponentialize. Thus if you can only remember part of the name
of something you can use this command to find the rest of the name.
Similarly, you could say apropos (tr_) to find a list of many of the
switches relating to the translator, most of which begin with tr_.
