If you entered a default IRC URI there, you can use just
channel or user names.
To send messages:
To a channel (for example, #chan ), irker accepts channel names of the form chan and
#chan .
To a password-protected channel, append ?key=thesecretpassword to the channel name,
with the channel password instead of thesecretpassword .
