Command

A list of commands that are available to players and what they do

/ap "Galaxy Name" - Engage Autopilot to specified galaxy.
/avoid "Galaxy Name" - Makes the autopilot avoid the specified galaxy (toggled). Can also be done by Shift+Right 
    Click on galaxy map.
/avoidteam "Galaxy Name" - Makes the autopilot avoid any galaxy owned by the same team as the galaxy specified (toggled)
/chatcolor <r> <g>  [r] [g] [b] - change the color of the chat frame.
/CLKL <value> - Set a minimum value to the lag killer for logicfps
/CLKU <value> - Set a maximum value to the lag killer logicfps.
/CP - Clear the profiler data. (will enable the profiler if disabled)
/DP - Dump the current profiling data to the logs. (will enable the profiler if disabled)
/FR - Do a quick reconnection, essentially forcing everything to reload from the server.( any command starting
    /f will do this.)
/GLKL <value> - Set a minimum value to the lag killer for fps.
/GLKU <value> - Set a maximum value to the lag killer fps.
/help - Display chat command help.
/ignore <player> - Add a player to your ignore list.
/like  <team teamname | playername> - remove all hate to target
/list - List ignored players.
/LKC <value> - Set a minimum value to the lag killer for both logic and render.
/LKU <value> - Set a minimum Value to the lag killer for both logic and render.
/Play - Play a recoded stream of everything happening on the client specify a number as second paramenter to 
    fast forward to that offset  (in millisecond). Middle click to stop, Left click to fast forward to 10 sec
    ago, Right click to fast forward 5 seconds(Double click for 2 minutes)
/Record - Record a playable stream of everything happening on the client.
/SaveCommands - Allow player to define a set of /commands to be executed on client start (only commands that do not 
    require a server  connection work).
/say [text] - Send a message to the focused channel.
/search <galaxy> - Center the universe map on a galaxy.
/unignore <player> - Remove a player from your ignore list.
/whisper <player> <message> - send a private message to a player. ~~ /w also works ~~

LKC sub commands below:

The higher the value is the more it try to reduce the lag generated by that type, higher than 1.0 is not guaranteed to work, but will have scaled impact on some things. Available types are:

/lkc gpureduce : That type is for reducing the quality without actually affecting the game-play (lk[1,15])
/lkc gpureduceaggressive : same as gpureduce except reach 1.0 at MS (lk[1,5])
/lkc gpuremove : That type is for removing stuff to improve the frame rate, but nothing critical yet (secondary effects like causing particles to update less, reducing 2 updates etc) (lk[5,15])
/lkc gpucritical : That type is the extreme stuff for the GPU (stop rendering transparency/projectiles and whatnot) (|k[10,15])
/lkc cpureduce : That type is for reducing the precision without actually affecting the game play (lk[1,15])
/lkc cpureduceaggressive : That type is for reducing the precision without actually affecting the game play. will reach 1.0 much faster (|l<[1.5])
/lkc cpuremove : That type is for removing stuff to improve the logic rate (lk[5,15])
/lkc cpucritical : That type is the extreme stuff for the cpu (|k[10,15])
/lkc rmbg : This control the quantity of background plane rendered 9lk[1,5])
/lkc slowgui : This control the rate at which the GUI is updated (|k[1,5])
/lkc starbg : This control the background stars intensity. Only update up to once per Ssec (lk[1,7])
/lkc lighting : This control the number of rendered lights, when ratio>=1. disable the lights alltogether (lk[1,6])
/lkc lagclipping : This control how far from your ship non important effects will be displayed (flags, nametag, thruster image etc will be removed from rendering if they are too far), having the camera zoomed out also reduce the distance on screen, will always ignore your target. (|k[1—5])
/lkc billboard : This control the clipping for some billboard effects (many weapons projectile, engines etc rely on those) (lk[6—10])
/lkc particles : This control how many particles are rendered. The higher this value, the less particles will be on screen. higher than1.01 will disable all particles (not recommended)) (lk[1—6])
/lkc refraction : This control the refraction bubble effects on explosion/warps, the closer the value is to 1, the less refraction's will be visible per second (>=1.0 disable it) (|k[6-9]0
/lkc projectiles : this control how many projectiles are rendered. The higher this value, the less projectiles will be on screen. Between 1.01 and 1.99 will disable all projectiles, higher than 2.0 will prevent any projectile from being removed (not recommended)) (|k[1-10])
/lkc bufficons : This control how many buff icons are rendered (The icons circling around your ship when affected by aura / tweaks). The higher this value, the less will be on screen. Above 1.01 will disable buff icons (lk[1-5]). P.S. this is a temporary measure andwill be removed once the buff icons rendering is optimized properly.
/lkc renderres : This control the resolution at which the game view is rendered. (lk[4-12])
/lkc renderfull 2 This control the resolution at which the game is rendered. (can only be changed manually using /lkc)
/lkc renderbg 2 This control the resolution at which the backgrounds are rendered. (lk[1—4])
/lkc simpleubase 2 This control weather user-base render their extension / trade bay or not (lk[5})
/lkc distortion : This control the distortion effects on explosion/lasers, change nothing from O to 0.99 (>=0.99 disable it) (can only bechanged manually using /lkc)
/lkc delaymap: This control how many seconds the client wait before requesting the next map bulk data in seconds (default is 0.1) (can only be changed manually using /lkc)
