Anything starting with a / is a command, unless it starts with
*two* / in which case the first one is removed and the rest is
sent as channel/query text.

Example: someone asks you where the password file is on UNIX. If you
reply "/etc/passwd", that would be considered a command. You type
"//etc/passwd" and the string "/etc/passwd" gets sent to the channel.

Anything that starts with / that isn't listed here gets sent to the
IRC server as-is, minus the /. That's why /who and /whois arent't
listed here, for instance.

/j <channel>
/join <channel>
Joins a channel, creates a new screen if possible. If a screen can't
be created, channel text will be sent to the [server] screen, and
"/m #channel" must be used, to send to the channel.

/m <nick|channel>
/msg <nick|channel>
PRIVMSG to nick or channel.

/q <nick> [<msg>]
/query <nick> [<msg>]
Creates a screen for PMs to/from <nick> if possible. If <msg> is
given, sends it to the <nick>.

/quit [<msg>]
Quits IRC with optional quit message.

/p [#chan] [<msg>]
/part [#chan] [<msg>]
Parts (leaves) a channel. If no #chan is given, the current screen's
channel is parted (if you're in a channel screen). If there's a screen
for the channel, it gets closed.

/ping [<nick>]
With no argument: ping the server. With arg: CTCP ping the nick.

/me
CTCP ACTION.

/ver <nick>
CTCP VERSION.

/info [<nick>]
With <nick>, CTCP CLIENTINFO. Without <nick>, INFO command for the
server.

/list <arg(s)>
This command will be sent to the server as-is. The only reason it's a
local command is so the argument can be required: sending LIST without
any arguments lists every channel on the server, which isn't useful.

/color <bg> [<fg>] [<border>]
Set colors. This should be on a per-window basis.

/quote <cmd>
Send raw IRC protocol.
