Crouching is a feature that reduces the area of your character, making you a smaller and less-visible target. This can make tasks such as defending Sentry Guns, sniping, pushing Payload carts and ambushing easier. Crouch-jumping increases the distance on jumps and also facilitates explosive jumping. Some obstacles require you to crouch-jump on top or over them as crouching in mid-air brings your legs and feet up.
When crouching, the character will move much slower than their default movement speed. But unlike running, you move backwards and forwards at the same speed. The default key for a crouch is Ctrl in the PC version, 
in the PlayStation 3 version, and 
in the Xbox 360 version. Crouching can be selected to toggle in the Options menu.
When crouching, your character will move 66% slower except when you are a Sniper who is scoped in (98.67% slower) or aiming an arrow (85% slower) or a Heavy with his Minigun revved (immobile).
Crouching does not increase your accuracy when firing a weapon, unlike in other Source games.

Update history
- Fixed headshots not always registering for crouched players.
- Fixed crouch-jump exploit that allowed players to get outside of the world
- You can now duck twice in the air. Scout double jumps reset the in-air jump counts
- Added "tf_clamp_airducks" convar, set to 1 by default
- Setting it to 0 will remove all constraints on ducking while in the air. Useful for servers running RJ challenge maps
- Added server ConVar "bot_crouch" to make bots crouch
- Fixed a case where crouching was used to see outside of the playable area. This could be exploited to place buildings at invalid locations.
