These are the basic stuff. Very simple, but cool anyway.

raphael - Narrator just says "Stanley" over and over again.

imabird - Makes it look like you are flying(Warning: Stanley does not actually fly).

facepunch - Don't even need console for this. Replace all textures with the Facepunch logo.

bark - Makes a bark sound whenever you hit the use key.

hideous - Opens a random page of the Team Fortress 2 wiki... for some reason.

secret - Adds something awesome when you select the Credits in the main menu.

vinh - Also does something cool in the Credits.

Now, let's move on to some of the harder, more complicated ones.

bind 5 "ent_fire !picker unlock; ent_fire !picker open" - Open any door by pressing 5

bind 6 "ent_fire !picker unlock; ent_fire !picker close - Close any door by pressing 6

mat_fullbright 1 - Makes the brightness of the map as bright as possible. Makes the last part of the Games ending a lot less scary. (NOTE: If anyone knows of a code that does the exact opposite, i.e., a code that makes everything dark, let me know. I'm kinda curious to see if there is one).

mat_fullbright 2 - Makes the game simpler looking. I haven't tested this code much so I will need to do more research.

mat_fullbright 3 - Do you hate textures? Or is your computer so slow that textures make the game lag? This code is for you. Gets rid of most textures, and makes the game look like it's made out of clay.

ent_create_portal_companion_cube - Spawns a friend that will never threaten to stab you, and, cannot speak.

thirdperson - Switches to third person view, in which it is revealed that Stanley is actually a glitchy Chell.

firstperson - It lets you jump. Haha just kidding. It brings back first person view.

ent_remove - Removes something if you point at it. Useful for removing doors but can also have some consequences. Might crash game if you remove something important.

fire_rocket_projectile - Fires a blue ERROR rocket. (WARNING: It can kill you.)

create_flashlight - Is mat_fullbright not your style? Then this is for you. This will light up an area that you point at.

ent_fire narrator kill - Ever wanted the Narrator to just shut the hell up? This command silences him. Although, sometimes the game is creepier without him there. 0.0

host_timescale ? - Replace ? with a number between 0.1 and 10. 1.0 is the default. What does it do? Well it's so funny that I won't spoil it. Let's just say you won't take the Narrator seriously when this code is in effect.

ent_fire zaxis_stormy togglesound - This will toggle the rain outside. It'll only work in the office though, so if you're thinking about using it in the last part of that Games ending to make the dark hallways less silent, sorry, but it won't work.

bind MWHEELUP "cl_fov 40"; bind MWHEELDOWN "cl_fov 90" - Now this code is a 2-in-1. Do you ever wanna read those papers on the ground, but the text is too small? This lets you zoom in and out with the mouse wheel.

ent_fire zaxis_paperpocalypse turnon - PAPER EVERYWHERE! Who threw all this paper everywhere!? Was it you, Bob?!?!

ent_fire zaxis_boxvillie turnon - Fills the office with BOXES! But they are just there for show. You can't pick them up or build a fort or do anything cool like that. Wish you could, but you can't.

crosshair 1 - Makes it easier to aim by putting a dot in the middle of the screen.

ent_teleport player - Teleports you to wherever you point at. Pretty neat, you can go to places you couldn't go before. (WARNING: BE VERY CAREFUL! TELEPORTING OUT OF MAP OR TO THE WRONG PLACE CAN CAUSE YOU TO GET STUCK OR YOUR GAME MIGHT CRASH!)

ent_fire bigcounter9 add 2000 - Want to go to the Art ending, but don't want to press that button for four hours? This will take you straight to it.

test_loop - This code crashes your game. You know, in case you want that to happen for some reason.

Now it's time to talk about maps. Some endings are in different maps. Here's how to go to them without having to walk there. Because walking is just too much work.

Just type "map"(no quotations) then the name:

map1 - Stanley's office

map - Last part of the confusion ending.

map2 - Takes you to the mind control facility.

map_death - Takes you to the crusher and Museum ending.

map_one - First part of the Confusion Ending(Right after the restart in the monitor room.)

map_two - Takes you to below the maintenence room where you see the monitor room.

redstair - Takes you to the creepy as hell Escape Pod ending.

seriousroom - Where do you think it leads? Lol.

testchmb_a_00 - Takes you to the Portal part of the Games ending, as well as the even creepier dark version of the original mod.(Seriously that part gave me nightmares 0.0)

blockbase - Takes you to the Minecraft part of the Games ending.

incorrect - The office that is deteriorating because you messed everything up!

freedom - TO FREEDOM!

buttonworld - Takes you to Heaven. BUTTONS......BUTTONS.....OHHHHH!

babygame - Takes you to that darn Baby Game.

thefirstmap - Second loop of the Confusion Ending.

theonlymap - Third loop of the Confusion Ending.

zending - Takes you to the Zending and the space room(SPAAAAAAAAAAAAAACE!)

There are codes that let you turn certain objects a different color. It works for some objects(mostly doors, buttons, and other objects).
All you have to do is bind a key to one of these codes, and then you can press that key to turn an object that color.

NOTE: I've had a bit of trouble with binding colors other than red, since red does not require a code. If anyone knows how to bind properly with the numbers, let me know.

ent_fire !picker color "
