Doom 3 Editing/Console Quick Reference
Quick reference:

Console command listing.
Cvar listing.

Quick tips:

To gain access to the level editor try this command-line: "doom3.exe +seta com_allowConsole 1 +set r_fullscreen 0 +set r_brightness 1 +editor".

To use the in-game editors try: "doom3.exe +seta com_allowConsole 1 +set r_fullscreen 0 +set r_brightness 1" and while in-game use ~ (or ctrl-alt-~ if you omit the com_allowConsole) to access the console. Load a map using "devmap <mapname>" and then check out the lights (editLights) and sounds (editSounds) editors--truly innovative stuff here!
