Miscellaneous Commands
Miscellaneous features not fitting anywhere else:
dired-find-subdir
Default: nil
If non-nil, Dired does not make a new buffer for a directory if it can be found (perhaps as subdirectory) in some existing Dired buffer.
If there are several Dired buffers for a directory, the most recently used is chosen.
Dired avoids switching to the current buffer, so that if you have a normal and a wildcard buffer for the same directory, C-x d RET will toggle between those two.
dired-vm
Bound to V if dired-bind-vm is t. Run VM on this file (assumed to be a UNIX mail folder).
If you give this command a prefix argument, it will visit the folder read-only.
If the variable dired-vm-read-only-folders is t, dired-vm will visit all folders read-only. If it is neither nil nor t, e.g., the symbol if-file-read-only, only files not writable by you are visited read-only.
If the variable dired-bind-vm is t, dired-vm will be bound to V. Otherwise, dired-bind-rmail will be bound.
dired-rmail
Bound to V if dired-bind-vm is nil. Run Rmail on this file (assumed to be mail folder in Rmail format).
