So most people seem to play with W,A,S,D setup but I don't
I use Delete for Left, End for Down, Page Down for Right, Home for UP, Insert for Lean Left, and Page Up for lean right.
Then I use the Number pad on the right to assign things like Flashlights, Reload.
\ Key is usually crouch, Enter key is usually prone, Ctrl is usually Jump.
Anyways I enjoy setting it up like this because I find it easier to distinguish where I am on the keyboard .
The Movement keys are seperate from the Jump/Prone keys which are seperate from my inventory keys.
I suggest trying it out I really enjoy playing like this
