| :!mv % %.bak

This is not better for a couple of reasons.

The first is that we are talking about an interractive shell, taking
over the tty for its command input.  For JOVE to do % replacement,
it would have to do the command input and feed the shell through a
PTY or something.  Ugh!

The second is that it would be yet another level of magic processing
of the command.  $1 already has a meaning to the shell, and the
shell can determine by its own rules (scope, quoting, etc.) when the
substitution is appropriate.

True.  I have just updated the JOVE documentation.
