How exactly does the SetBinding function work? Does it assign a new key to what used to be W? Or does it just make W assign to the new thing without changing anything in the Esc menu -> keybindings. Sorry it's hard to word this question.

i.e. Say i have
Move foward bound to W. Does calling /script SetBinding("W", "MACRO Follow") simply make an invisible bind of W -> follow, or does it change "move foward" -> follow?
