Variable: gnus-agent-consider-all-articles
gnus-agent-consider-all-articles is a customizable variable defined in
gnus-agent.el.gz.
Value
nil
Documentation
When non-nil, the agent will let the agent predicate decide whether articles need to be downloaded or not, for all articles. When nil, the default, the agent will only let the predicate decide whether unread articles are downloaded or not. If you enable this, groups with large active ranges may open slower and you may also want to look into the agent expiry settings to block the expiration of read articles as they would just be downloaded again.
This variable was added, or its default value changed, in Emacs 22.1.
