FILTER SUMMARY MODEThe file SYS:PUBLIC;FILTER-SUMMARY provides a "Filter Summary Mode"for mail buffers similar to that provided by the mail reader in Release 2.To use this mode you must load the XLD file, read your mail file, and enterM-X Filtered Mode.  To make this mode your default, set the variableZWEI:*MAIL-SUMMARY-MODE* to :FILTERED in your LOGIN-INIT file.Filter Summary Mode is an interface for managing mail messages similar tothat provided by DIRED for managing files.  A "Filter" is a test performedon messages to select only those messages that meet certain criteria.Messages can be filtered based on keywords, attributes, text content,sender, recipients, and date.A filter summary initially contains one line for each mail filter definedin your mail file -- no message summary lines are displayed initially.Filters can be "expanded" to show the summary lines for messages that"pass" a filter.  New filters can be created and saved in your mail file.Existing filters can be deleted from the display and from your mail file.COMMANDS FOR FILTER SUMMARIESThe following command operatate on filter summaries.
