* doc/lispref/intro.texi (Printing Notation): Clarify what
"execute code" means in this context. (Bug#43463)
Many of the examples in this manual print text when they are
evaluated. If you execute example code in a Lisp Interaction buffer
-(such as the buffer @file{*scratch*}), the printed text is inserted into
+(such as the buffer @file{*scratch*}) by typing @kbd{C-j} after the
+closing parenthesis of the example, the printed text is inserted into
the buffer. If you execute the example by other means (such as by
evaluating the function @code{eval-region}), the printed text is
displayed in the echo area.
