@cindex Conditional with @code{if}
-A third special form, in addition to @code{defun} and @code{let}, is the
-conditional @code{if}. This form is used to instruct the computer to
-make decisions. You can write function definitions without using
-@code{if}, but it is used often enough, and is important enough, to be
-included here. It is used, for example, in the code for the
-function @code{beginning-of-buffer}.

The basic idea behind an @code{if}, is that @emph{if} a test is true,
@emph{then} an expression is evaluated. If the test is not true, the

In Emacs Lisp programs used for editing, the @code{save-excursion}
function is very common. It saves the location of point,
