You can use most normal Emacs commands to move forward and backward in
the buffer. Some keys are rebound to functions that take advantage of
the fact that the buffer is a PCL-CVS buffer:
<SPC>
n
These keys move the cursor one file forward, towards the end of the
buffer (cvs-mode-next-line).
p
This key moves one file backward, towards the beginning of the buffer
(cvs-mode-previous-line).
