I switched to Fish a couple years ago, and I love it too — the only thing I ever find myself missing from bash is `!!`. The (new) Alt+S keybind to prepend `sudo` to a command covers many of these use cases, but not all of them. For example, sometimes I want to re-run the last two commands; in Bash I could do `<up><up> && !!` but there doesn’t seem to be a good way to do this in Fish without having to re-type one of the commands.
Alt+Up is great for recalling individual arguments, but am I missing something or is there no way to recall a whole previous line in-place, without overwriting what’s currently on the command line?
