gnus: Interactive

 
 9.2 Interactive
 ===============
 
 ‘gnus-novice-user’
      If this variable is non-‘nil’, you are either a newcomer to the
      World of Usenet, or you are very cautious, which is a nice thing to
      be, really.  You will be given questions of the type “Are you sure
      you want to do this?” before doing anything dangerous.  This is ‘t’
      by default.
 
 ‘gnus-expert-user’
      If this variable is non-‘nil’, you will seldom be asked any
      questions by Gnus.  It will simply assume you know what you’re
      doing, no matter how strange.  For example, quitting Gnus, exiting
      a group without an update, catching up with a group, deleting
      expired articles, and replying by mail to a news message will not
      require confirmation.
 
 ‘gnus-interactive-catchup’
      Require confirmation before catching up a group if non-‘nil’.  It
      is ‘t’ by default.
 
 ‘gnus-interactive-exit’
      If non-‘nil’, require a confirmation when exiting Gnus.  If
      ‘quiet’, update any active summary buffers automatically without
      querying.  The default value is ‘t’.
