Documentation

Non-nil means progressively narrow the set of messages produced by summary.

This allows to apply the summary criteria on top one another, thus progressively narrowing the selection of the messages produced by each summary criteria. For example, applying rmail-summary-by-senders on top of rmail-summary-by-topic produces a summary of messages with the specified Subjects that were sent from specified sending addresses. This way, the user can apply one summary on top of another, and keep narrowing the resulting list of messages.

This variable was added, or its default value changed, in Emacs 29.1.

Probably introduced at or before Emacs version 29.1.
