The Supreme Commander user interface is quite extensive. This list and its subpages contain only commands from an unmodified latest offical patch release (Currently patch 3223)
SupCom currently does not support reassigning keys (the developers have acknowledged that this would be usefull though) or commands.
This reference lists Keyboard and Mouse commands separately, divided and ordered by function.
Keyboard Commands 
Edit
The designers have tried to assign keys "mnemonically", ie. the letter is the beginning of the command. Unfortunatly some letters are overused, so the second letter or a "similar" letter is used. It is the letter that is entered, not the keyboard key position, ie. for non-US keyboards you may find some keys awkward (f.ex. must use AltGR-8 for "[" )
Ingame you can get most of these by pressing F12
Basic unit commandsEdit
The same command works slightly different depending on unit given to, particularily stationary or mobile units. Most commands require a left-click where/on what the action is to be performed. Remember commands can be queued up by using Shift-left-click when setting destination.
| Key | Command | Additional notes |
| Most units | ||
|---|---|---|
| S | Stop | All: Stop motion. Clears all way points. Clears build queues |
| M | Move | Mobile units: Move. Factories: Set rally point (Built units move to) |
| A | Attack | Fire and follow until enemy dead |
| P | Patrol | Mobile units: Patrol. Factories: Built units made go on patrol. |
| I | Guard/Assist | Engineers: Keep unit at full health. Mobile units: Follow and fire on attackers of unit. Factories (assisting other factories): Build same units |
| Z | Unit Pause | Engineer/Factories: Pause building or upgrading. |
| Ctrl-K | Suicide | All: Selfdestruct! (Other units standing too close may damage, friend or foe) |
| Only applicable to few units | ||
| R | Repair | Engineer/ACU/SCU |
| E | Reclaim | Engineer/ACU/SCU: Get the mass/energy from tree, stone etc. Can recycle material from own units, too. |

| B | Build | Engineers/ACU/SCU and factories: Enters special keyboard entry mode. See table below. Leave with ESC key. |

| L | Launch Tac.Miss. | Tactical Missile Launchers (stationary unit, some ships, and some ACUs): Fire one missile (must be built) |
| N | Nuke | Strategic Launcher and nuclear sub: Fire one nuclear missile (must be built) |
| [ | Toggle Fire state | Attack&Chase or just return fire. The "nonagressive" state means the Attack command does not work. |
Build ModeEdit
The B key enters a special keyboard entry mode - Build mode. End build mode with ESC.

Mouse commandsEdit
"Left to select, Right to Command" is the idea from the manual and tutorials in the game. There are exceptions. Mouse commands are very context sensitive - what you currently have selected, what command you issued via the menu or keyboard, and what you are pointing at. Left-click on a menu item will not change the select
A right-click on its own, will do the default command for that unit on that target, typically Attack for an enemy and something (relatively) usefull for a friendly unit. (Some commands are only available through right-click?) If you have used a keyboard command or a menu command then you have to left- click on the location or target you wish to apply this to.
Mouse movement (Mouse over)Edit
| (Nothing pressed) | Just move the mouse. You get brief info on units you mouse over. For stationary units shows action radius. |
| . | If you reach the screen edges, map scrolls (adjustable in Options) |
| SPACE-bar held down, zoom level is "close enough" | Shift the camera viewpoint. (The camera "jumps backwards" if you are positioning it "in front" of a mountain.) (You can set and release a viewpoint with Ctrl-V) |
Left-clickEdit
| No command | Nothing selected | Click on ground | Does nothing |
| Select Patrol (or related option), then Shift click to mark waypoints. | Waypoints Marked | Click on Unit | Unit is selected |
| Click on ground and hold, then drag across desired units. | Units selected | Click on ground | Units are deselected |
| Click on option | Navigate through the menu | Click on a unit (after you already select one). | Units deselected, new unit selected. |
| Active command (Move, Patrol, Build ...) | Units Commanded | Cick on Ground or Unit (appropiate for command) | Units immediatly do the command |
