Problem / Steps to reproduce

Reference #3678

Ctrl-r conflicts with bash's reverse-search-history (C-r). FZF doesn't have an option to disable this binding

Add an option to skip fzf's Ctrl-r binding by setting a variable to an empty string, ie

FZF_CTRL_R_COMMAND= eval "$(fzf --zsh)"

[junegunn]

All the bindings override the default bash ones. But the important difference is that ALT-C and CTRL-T change the default behavior (capitalize-word, transpose-chars) but CTRL-R enhances the default reverse-search-history, so few want to turn it off (CTRL-R is one of the most loved features of fzf). Also, there is currently no FZF_CTRL_R_COMMAND, so introducing it just for disabling CTRL-R doesn't seem ideal.

If you do want the original reverse-search-history over the fzf's one, you can easily restore it like so:

eval "$(fzf --bash)"
bind '"\C-r": reverse-search-history'
