The @kbd{?} key (@code{calc-help}) displays a series of brief help messages.

+Some keys (such as @kbd{b} and @kbd{d}) are prefix keys, like Emacs's
@key{ESC} and @kbd{C-x} prefixes. You can type
@kbd{?} after a prefix to see a list of commands beginning with that
prefix. (If the message includes @samp{[MORE]}, press @kbd{?} again
of the theory of random number generators and their measurement and
characterization.

+If @code{RandSeed} has no stored value, Calc calls Emacs's built-in
@code{random} function to get a stream of random numbers, which it
then treats in various ways to avoid problems inherent in the simple
random number generators that many systems use to implement @code{random}.
Calc is controlled by many variables, most of which can be reset
from within Calc. Some variables are less involved with actual
-calculation and can be set outside of Calc using Emacs's
+calculation and can be set outside of Calc using Emacs'ss
customization facilities. These variables are listed below.
Typing @kbd{M-x customize-variable RET @var{variable-name} RET}
will bring up a buffer in which the variable's value can be redefined.
