Registry of Ediff Sessions
**************************

   Ediff maintains a registry of all its invocations that are still
_active_.  This feature is very convenient for switching among active
Ediff sessions or for quickly restarting a suspended Ediff session.

   The focal point of this activity is a buffer called _*Ediff
Registry*_.  You can display this buffer by typing `R' in any Ediff
Control Buffer or Session Group Buffer (Note: Session Groups), or by
typing `M-x eregistry' into the Minibuffer.  The latter would be the
fastest way to bring up the registry buffer if no control or group
buffer is displayed in any of the visible Emacs windows.  If you are in
a habit of running multiple long Ediff sessions and often need to
suspend, resume, or switch between them, it may be a good idea to have
the registry buffer permanently displayed in a separate, dedicated
window.

   The registry buffer has several convenient key bindings.  For
instance, clicking mouse button 2 or typing `RET' or `v' over any
session record resumes that session.  Session records in the registry
buffer provide a fairly complete description of each session, so it is
usually easy to identify the right session to resume.

   Other useful commands are bound to `SPC' (next registry record) and
`DEL' (previous registry record).  There are other commands as well,
but you don't need to memorize them, since they are listed at the top of
the registry buffer.
