Journal Files

[CPH%MIT-OZ@MIT-MC.ARPA]

I have been trying to use the JOURNAL library to keep records of my
keyboard interactions so I can analyze what character sequences I most
often type while editing.

Unfortunately, the library doesn't seem to work as advertised.  It is
claimed in the EMACS manual that the journal file is updated every 50
characters.  As far as I can tell, this is completely untrue.  The
output file is created, empty, and NEVER is any information written in
it unless M-X End Journal File is invoked.

Does anyone know anything about this that I don't?  Is there some
aspect of the operation that I have overlooked, or is the library just
broken?  I really want to get records of my editing sessions to
analyze.
