5.1.3 Persistent Marks

There are ten persistent marks, `!', `N', `n', `U', `u', `A', `a', `F', `f' and `$'.

The persistent mark indicates the message's status and it is saved. Each persistent mark indicates:

`N'

It is new message.

`n'

It is new message. It differs from `N' that message with `n' is already cached.

`U'

It is unread message.

`u'

It is unread message. It differs from `U' that message with `u' is already cached.

`!'

It is message already read. It differs from message without mark that message with `!' is not cached yet.

`A'

It is already replied message.

`a'

It is already replied message. It differs from `A' that message with `a' is already cached.

`F'

It is already forwarded message.

`f'

It is already forwarded message. It differs from `F' that message with `f' is already cached.

`$'

It is a message with some global flag. It is convenient to put this mark on the messages to remember (If you want to remember to write a reply for the message, for example) because this mark remains after you exited Emacs. Messages with the `$' mark can be reviewed in the `'flag' folder even the message itself is deleted in the actual folder. You can put global flag by typing $ or F key.

`None'

If the message is read and cached (or local message),there are no persistent mark.

`N', `U', `!', `A', `F' indicates that the message have no cache. Messages with the marks other than these, you can read them in the offline status even they are in the IMAP folder or netnews folder.

Among messages with persistent marks, ones with marks specified by wl-summary-expire-reserve-marks are excluded from the expiration (as a function of wanderlust) explained later. See section 9. Automatic Expiration and Archiving of Messages.
