This is available in bash/sh by setting this in your ~/.inputrc file:

  "\e[A": history-search-backward
  "\e[B": history-search-forward
  "\e[C": forward-char
  "\e[D": backward-char

I used bash first, then zsh. You have to try fish, it shows a "ghost" of the first matching autocompletion on the same line, which changes dynamically as you type. It also has a cool memory effect for figuring out history completions based off the directory you are in.

Like csh on FreeBSD, alt+(up/down) can be used to search history for arguments instead of lines, so if you do something like

   touch some/long/directory/path/to/file
   ....
   rm so<ALT+up>

fish will search all individual arguments (correctly handling quoted spaces, etc) for arguments starting with "so" and it'll suggest the path in question, even though the head here (`rm`) differs from the original (`touch` in this case).

That sounds a bit dangerous, especially with rm.

As always, with great power comes great responsibility I guess.

Or just use ctrl-R et al.
