Alter Section

This dialog window allows you to set options for each individual message section.

For maximum convenience, all buttons in this window respond to Command-key equivalents: Command-P takes you to the Previous entry, Command-B toggles the backup setting, Command-C Cancels and so forth.

Limit sets the maximum number of messages allowed in the currently selected section.

Age sets the maximum number of days a message is considered valid.

Backup determines whether or not deleted messages are archived to a text file.

Save records the changes for the currently selected section and exits.

Cancel ignores the changes for the currently selected section and exits.

All four movement buttons — Previous, Next, First and Last — automatically save the settings for the  currently selected section.

Help summons this Help window.
