OTClient wasd Walking

[CoolBuys1290]

Please help me toggle chat with the enter key when enabling wasd walking. I don't know where to paste this code:

function hotkeyToggleChat()
  consoleToggleChat:setChecked(not consoleToggleChat:isChecked())
  if consoleToggleChat:isChecked() then
    disableChat()
  else
    enableChat()
  end
end
