Problem / Steps to reproduce

Hi

I'd like to use vim as a previewer for fzf

fzf --preview='vim -RMn --not-a-terminal {}' --bind shift-up:preview-page-up,shift-down:preview-page-down

But I'm encountering two issues:

• On the top there are the file and folder infos, with also some ANSI characters , that are putted over the text, ruining the readibility if the preview
• The --bind flag seems do not work

So, I'd like to use vim for previews in fzf, with the same behavior of other tools, like bat or cat
