The list of commands in the manual is out-of-date and is missing a few. Here's what's missing, in case anyone is interested:
friendkey................friendkey management
key........................keychain management
gunner...................invite a gunner to man turrets
navroute................plot a route on the navmap; save/load routes
voicechattoggle.......(I couldn't get this to work)
voicemute..............ignore for voicechat
voiceunmute...........unignore for voicechat
+ptt.......................Push-to-Talk (voicechat)
-ptt
j.............................same as /join
say_station..............chats to bar
missionchat..............displays mission log
mission....................commands for the current mission (e.g. /mission abort)
missionmsg..............Obsolete?
stoprecording............video recording (not fully implemented yet?)
startrecording............video recording (not fully implemented yet?)
toggleautoaim............enable/disable auto-aim
AccelTouch.................Analog control
+LookPress................Analog control?
sndrecordstop.............(I couldn't get this to work)
sndrecordstart.............(I couldn't get this to work)
sndrecordtoggle...........(I couldn't get this to work)
sndshow.....................displays names of sounds being played
RadarNone..................Unselects radar target
RadarPrevNearestPowerup......Selects next floating cargo drop (doesn't work very well)
RadarNextNearestPowerup......Selects previous floating cargo drop (doesn't work very well)

Built-in aliases:
say_help..........chat to help channel
hail..................send hail message to target
hudscale...........rescales hud (cycles thru 7 presets)

-- Radar Toggles --
togglehostiles
togglefriendlies
toggleobjects
togglestations
togglecargo
togglemissiles
showall

Also note that the following commands listed by the manual are no longer valid:
sector
netquery
profile
MusicToggle
Weapon7
Mine2

Huh, odd, I could have sworn RadarNone was in the list before.

I do know that +LookPress is not of much use to most people and is used I think exclusively with touch screens when in turrets to recenter the view when removing your finger.

Bugs?
