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).
