Setting key binds in Rust is pretty useful and easy because it will stop hurting you if you farm a lot, if you hate holding cross 1, and if you hate holding the run button.
Setting up autorun is very easy; all you have to do is type F1 until the menu pops up and then type:
BIND Q Forward; SPRINT
Once the command is typed, you can turn on the autorun whenever you want in the game.
Auto crouch is probably the best keybind because you can bind it with the autorun. Autorun plus auto crouch is pretty good if you are trying to go deep on someone. To set this keybind, you have to press F1, and then type:
BIND C DUCK
Auto Farm and Auto Hit
To set up auto farm or auto attack, you need to type the following command, after you open a command menu by pressing F1:
BIND Z ATTACK; DUCK
