Does fish have its own inputrc ?

I'm sure it uses inputrc or similar, giving you a thing like:

  $if mode=emacs
  "\e[A": history-search-backward
  "\e[B": history-search-forward
  $endif

aka, type "fish" and press up arrow to only go through history that starts with "fish"

also, how would you configure fish to use something that doesn't lean on arrows? ^r has its own useful power that can be separate from my use-case of arrows mentioned above, if not just bc you don't have to move off the homerow ;)
