disable chat?

Hello, well i want to know if there is a way to disable the Chat, since everything i type appears in the chat, even if i want to move with 8, 4, 6 and 2, its typed in the chat which is very annoying, what can i do about this?

another question is, its possible to change the moving keys to another ones? for example WASD

thanks

Disable NumLock on your keyboard to avoid typing numbers when you walk, but the best method to control your character is with a controller, as you can't remap the keyboard or mouse controls.
