Use the SCAN command to get a quick summary of the messages on the currently
active subboard. The scan shows the message number, the date the message was
posted, the name of the sender, and the title of the message. You may scan
messages in forward or reverse direction by replying to the Scan prompt with
'F' for forward or 'R' for reverse. Notice that you can abort a scan at
anytime simply by pressing <spacebar> or <ctrl-c> keys.
Refer to the Read command for reading messages, New for scanning new
messages only, and List and Jump commands for selecting a new message
subboard.
