example, pressing the @key{TAB} key automatically indents the line the
cursor is on by the right amount. A command to properly indent the
code in a region is customarily bound to @kbd{M-C-\}. Indentation is
! designed so that you can see which elements of a list belongs to which
list---elements of a sub-list are indented more than the elements of
the enclosing list.

Another way to think about @code{let} is that it is like a @code{setq}
that is temporary and local. The values set by @code{let} are
automatically undone when the @code{let} is finished. The setting
! only effects expressions that are inside the bounds of the @code{let}
expression. In computer science jargon, we would say ``the binding of
a symbol is visible only in functions called in the @code{let} form;
in Emacs Lisp, scoping is dynamic, not lexical.''

Before looking at the code, let's consider what the function
definition has to contain: it must include an expression that makes
the function interactive so it can be called by typing @kbd{M-x
! beginning-of-buffer} or by typing a keychord such as @kbd{C-<}; it
must include code to leave a mark at the original position in the
buffer; and it must include code to move the cursor to the beginning
of the buffer.

@cindex Asterisk for read-only buffer
@findex * @r{for read-only buffer}
! The asterisk is for the situation when the buffer is a read-only
! buffer---a buffer that cannot be modified. If @code{insert-buffer} is
! called on a buffer that is read-only, a message to this effect is
! printed in the echo area and the terminal may beep or blink at you;
! you will not be permitted to insert anything into current buffer. The
! asterisk does not need to be followed by a newline to separate it from
! the next argument.

@findex defcustom
You can specify variables using @code{defcustom} so that you and
! others can then can use Emacs' @code{customize} feature to set their
values. (You cannot use @code{customize} to write function
definitions; but you can write @code{defuns} in your @file{.emacs}
file. Indeed, you can write any Lisp expression in your @file{.emacs}

The answers can be found by a quick test. When @code{(% -1 5)} is
evaluated, a negative number is returned; and if @code{nthcdr} is
called with a negative number, it returns the same value as if it were
! called with a first argument of zero. This can be seen be evaluating
the following code.
