We actually do have

  bindkey '\e[A'  up-line-or-search

in there. However, we might need to do this too:

  bindkey '\eOA'  up-line-or-search

...keyboard handling is something that we want to improve for a long
time. But it's not trivial to get right and especially to convert our
existing bindings, without breaking backwards compatibility (too much).


Report if the additional binding enables that feature for you.
