<p>The line number provides a quick way to move around in the history buffer.
To get a previous line without laboriously typing M-p over and over,
simply type the line number (without control or meta bits), then M-.

In repl.scm, each value is retained in variables of the form '&lt;n&gt; where n
is the number shown in the prompt.
