When typing messages in game, or writing notes, any time you need to use the keyboard to write text, your character will respond in kind. Only applies to lean left/lean right, walk forward.
Unsure whether this applies to other players viewing me. Probably does as I move around.
hit "/" to chat. Or write a note on paper.
type a message. Recommend looking at how the (by default) Q, E and W keys react.
notice how your character is responding
-on Q my character leans left.
-on E my character leans right.
-on W my character walks forward.
-on ASD, my character does nothing and I type properly.
Try tapping W once. It will register the W in chat as well as step you forward.
Try holding down W. You won't move at all and your chat will react appropriately.
Try taping Q. Your character will lean left, and Q will appear on chat.
Try double-tapping Q. Your character will not 'lock' leaning left, yet two Qs will appear in chat.
Now try double tapping Q, but hold Q on the second tap, before letting go. You will remain leaning left, and more than 2 Qs will have showed up in chat.
Repeat to confirm for Right lean.
