Following upgrade to Ubuntu 18.04 and reinstallation of software inclung FZF.
Ctrl+r does not work for me in zsh, although it does if I switch back to bash. I have reinstalled fzf a couple of times without changing this. Any ideas?

[xPrzybyLx]

For me FZF does not work on Vagrant ZSH shell.

[deepredsky]

fzf adds completion files for your shells like ~/.fzf.bash, ~/.fzf.zsh and loads them by configuring corresponding rc file. For example, it will add

[ -f ~/.fzf.bash ] && source ~/.fzf.bash

in ~/.bashrc

[ -f ~/.fzf.zsh ] && source ~/.fzf.zsh

in ~/.zshrc

I think in ur case, ur missing these lines in ur .zshrc file or the completion files as missing.

u may run the install script again to add the bindings & completions for ur shells

I hope that helps

[dboneham]

Thanks Rajesh.

However, this not the answer as the Alt-C and Ctrl-T bindings work
correctly in zsh.

I did reinstall fzf just to make sure, but the Ctrl-R binding (and only
that binding) continues not to work. This suggests to me that something in
the Ctrl-R part of the zsh binding script is not quite right - but I cannot
identfiy any error.

Best wishes

@dboneham its possible that the key was bound to something else ( for example in ur zshrc or via another plugin ). Can u check like this

bindkey | grep fzf

u should get something like this in result:

"^I" fzf-completion
"^R" fzf-history-widget
"^T" fzf-file-widget
"^[c" fzf-cd-widget

[dboneham]

Rajesh

This is what I get.

"^T" fzf-file-widget
"^[c" fzf-cd-widget

I inspected the bindkey results and Ctrl-R is bound to
history-incremental-search-backward.

Ctrl-I is bound to expand-or-complete-with-dots.

No clue as what is bringing about these bindings. I suspect it may be my
zshrc, which I copy below.

You could try moving [ -f ~/.fzf.zsh ] && source ~/.fzf.zsh to the end, or just add the binding to different key to see if that works. One of ur plugins might have overwritten fzf bindings for "^R"

[dboneham]

Thanks.

The solution was indeed just to bind Ctrl-R to fzf-history-widget I noticed
that an alternative binding for history-incremental-search-backwards was
already in existence, so no loss of functionality. Not that I sue that
functio anyway..Inbox

My guess is that the zsh completion plugin overwrite the binding. So I have
just reversed that. I may need to figure out a way of making my binding
permanent if it overwrites again

Fixed it permanently by adding a line to my zshrc at the end binding the
key to the fzf widget.

Thanks again

glad it worked out. Can u close this issues. Thanks

[mnowotnik]

Just remove

\C-y\ey part from the bind command in the ~/.fzf/shell/key-bindings.bash:

bind '"\C-r": " \C-e\C-u\C-y\ey\C-u`__fzf_history__`\e\C-e\er\e^"'

and it works like a charm.

[Congee]

I found bindkey -e binds "^R" to history-incremental-search-backward. The key binding order matters.

[lyc2345]

I have a question about this topic too.

I install fzf through Homebrew and I add fzf in zshrc.zsh plugin like this plugins=(fzf)

I saw the suggestion is to put [ -f ~/.fzf.zsh ] && source ~/.fzf.zsh in the end of zshrc.zsh. But I don't have any .fzf repo in my home directory. So this suggestion is not suit for me. I also saw some tutorial is git clone fzf repo in home directory as .fzf

I have 2 questions.

1. Can I just use oh-my-zsh plugins fzf or the Homebrew installed one?
   Because I don't want to have same fzf repo in everywhere.

1. If first question is No. Is any way to solve my problem or the only way is clone a repo in home directory?

Thanks for reply

[lyc2345]

Reply my question. Install fzf using Homebrew like

# To install useful key bindings and fuzzy completion:
$(brew --prefix)/opt/fzf/install

It add .fzf.zsh and .fzf.bash in home directory so now it can be sourced

[berthin]

In my case the .fzf.zsh file had the keybinding disabled, I had to enable them:

  # Key bindings
  # ------------
  source "/home/user/.fzf/shell/key-bindings.zsh

then you can try: source ~/.fzf.zsh (or bash)

In my case too, after a fresh install of ubuntu, I faced the same issue,
at pressing "ctrl+r" was bck-i-search: opening. Luckily it worked.

source "/home/$(whoami)/.fzf/shell/key-bindings.zsh"
[ -f ~/.fzf.zsh ] && source ~/.fzf.zsh
Paste above line in 'vi ~/.zshrc' file and don't forget to run this command afterwards 'source ~/.zshrc'

[rr326]

If you are trying to install for the raspberry pi, key bindings are not installed automatically!

Add this to .zshrc: source /usr/share/doc/fzf/examples/key-bindings.zsh

You can see this yourslf:

 apt-cache show fzf
...
Refer /usr/share/doc/fzf/README.Debian for quick instructions on how to
 add keybindings for Bash, Zsh, Fish to call fzf.

cat  /usr/share/doc/fzf/README.Debian 
...
Zsh
===

Append this line to ~/.zshrc to enable fzf keybindings for Zsh:

   source /usr/share/doc/fzf/examples/key-bindings.zsh
