Keywords are:  'beep'

Format:
beep <character name>

The beep command will send a control-G to a specific character, along
with a short message indicating to them that you wish to talk to them.

This command was historically used to get the attention of sleeping
players back when you could not send tells to sleeping people.

This command should not be abused by repeatedly beeping someone.  The
ignore command can be used to ignore beeps as well as tells.
