mode and its cross-references

mode

channel [<chan>] mode *|+...-...           (`mode *' is default.)
 If not set to `*' then whenever I'm alone in the channel I'll set
 and unset the channel modes specified.  Only the modes imnpst are
 supported.  Precede one or more mode letters with + to set, - to
 unset; any letters not mentioned will be left alone.
