-### Delete buffers from `:Buffers`
-
-This customization is an _attempt_, that sometimes doesn't work, to make the key `D` in `:Buffers`' interface, delete buffers. See the issues reported with this customization [here](https://github.com/junegunn/fzf.vim/pull/1044#issuecomment-651199164). An additional change this does to `:Buffers`' interface, is to make fzf reload the list of available buffers upon deletion, while allowing to delete multiple buffers as well. The requirements are:
-
-- https://github.com/mhinz/neovim-remote .
-- fzf.vim with this PR merged: https://github.com/junegunn/fzf.vim/pull/1044
-- fzf 19.0 or later.
