4.1.1.1 Check new, unread number

Folder mode looks like this. (In XEmacs, it looks much nicer ;-))

Each line means:

folder-name:new-number/unread-number/all-number

s key on the folder line updates these numbers. It changes its color if it has many new messages.

The whole folder mode is a folder group named `Desktop'. Folder group open/close by return key. A operation to a folder group is treated as operations on the children folders. For example, when you type s on `[-]Emacsen', six children folders update its unread number status.
