Parkour:

Crouch walk - Crouch walking halves your hitbox and silents your footsteps, while still being able to move. You can also move under low passages.

Rolling - While moving left or right, pressing crouch will make your character roll.

Wall jumping - At the peak of your jump, jump again while against a wall to walljump.

Double jump - Press jump again while in mid-air. This will render you defenseless until you land.

Crouch jump - Holding crouch while in mid air. This lets you fall faster and land silently and will let you minimize damage from explosions while launching yourself at a later time.

Tuck and roll - Holding left or right while landing a crouch jump will do a silent rolling land.
