These are great, thank you.

I have one issue: When I select an entry and hit Return, the entry appears above the prompt rather than in the prompt. Here's an example. This doesn't happen for normal fzf commands. Do you know a way off hand to make the entry stay in the prompt?

I don't, sorry.

Thanks for the code anyway!

Edit: revised & expanded here.

Here's the version that adds the entry to the commandline. I'm sure there's a better way of doing this in fish — feel free to critique.

# Deciphered from fzf-file-widget. Somewhat unclear why it doesn't exist already!
function fzf_add_to_commandline -d 'add stdin to the command line, for fzf functions'
  read -l result
  commandline -t ""
  commandline -it -- (string escape $result)
  commandline -f repaint
end

Awesome work 👍 just want to mention fzf.fish also provides key bindings for git log, git status and more.
