Listing [[lst:setup-vertico-mode]] sets up =fido-mode= and =vertico-mode=. Listing
See the [[yt:hPwDbx--Waw][Vertico extensions for Emacs]] video for an overview. Listing
[[lst:setup-vertico-mode]] sets up =vertico-mode= without using the
=vertico-directory= extension (less is better!). Listing
[[lst:prune-file-name-history]] allows to prune non-existing files from the file
name history. NOTE: The src_emacs-lisp{(describe-function 'savehist-mode)}
documentation explains why it is best to turn on =savehist-mode= in the
=user-init-file=. BUG: Adding ~kill-ring~ to ~savehist-additional-variables~
does not save ~kill-ring~ from an Emacs session to the next session, contrary to
the src_emacs-lisp{(describe-variable 'savehist-additional-variables)}
name history.
NOTE: Play with =vertico-buffer-mode=, =vertico-flat-mode=, =vertico-grid-mode=,
=vertico-indexed-mode=, =vertico-mouse-mode= (not easy to use with my trackpad),
=vertico-reverse-mode=.
NOTE: The src_emacs-lisp{(describe-function 'savehist-mode)} documentation
