If you wanna use cheats: Esc -> Options -> Keyboard/Mouse -> Allow Developer Console.
Press the ` key (upper-left corner of your keyboard) to open the Developer Console. Most of these codes will not work unless cheats are activated (sv_cheats 1).



Note: When you turn on sv_cheats, all progress for the session is nulled, including story progression and achievements.

• Only the host can enable cheats in Co-op mode. The host is always Atlas, the blue robot.
  
• The "sv_gravity #" and "cl_showfps #" commands are examples of commands that always work, even if cheats are off.
  
• Removing certain objects or removing your partner WILL crash the game (ent_remove).
  
• The gel blobs will spawn in all maps, but they won't actually function properly in maps that do not use mobility gels.

You can bind keys on your keyboard as shortcuts for using cheats using this format:

bind "insertkey" "insertcommand"

Note: You can also bind keys in Left for Dead using the same commands, I remember binding keys to make the characters repeat their words over and over example Tank, Hunter, Smoker boomer etc. Value patched it latter on in Left 4 Dead one.

For example, if you wanted to create a hotkey for the "kill" command to the key M, you would have to type this into your Developer Console:

bind "m" "kill"

So now every time you press M, you will die! Remember not to bind keys such as WASD, FQTEC, Spacebar, SHIFT, TAB, since those are neccessary in regular gameplay. If you want to undo a bind:

unbind "insertkey"

Binding is useful, because you don't have to repeatedly open the Developer Console in order to execute commands. Spawning large quantities of cubes is easy with binds!

If you would like to have an easy method of binding all of your keys at once, open up your Program Files and look for: Steam -> steamapps -> common -> portal 2 -> portal2 -> cfg.

There, you can add and save your own cfg file. Open up Notepad and type in a list of all your binds. Save it and name it "Binds.cfg" (make sure that it really is a cfg extension). Run Portal 2, open your Developer Console, and type:

exec "Binds"

Use the semicolon ( ; ) to execute multiple commands at once. Useful for tricks, such as killing your partner without him being able to retaliate with cheats of his own:

sv_cheats 1; fire_rocket_projectile; sv_cheats 0

And spawning a huge line of paint:

"ent_create_paint_bomb_jump; ent_create_paint_bomb_portal; ent_create_paint_bomb_speed; ent_create_paint_bomb_jump; ent_create_paint_bomb_portal; ent_create_paint_bomb_speed; ent_create_paint_bomb_jump; ent_create_paint_bomb_portal; ent_create_paint_bomb_speed; ent_create_paint_bomb_jump; ent_create_paint_bomb_portal; ent_create_paint_bomb_speed"
