:END:
Listing [[lst:enable-vertico-mode]] configures and enables =savehist-mode= and
enables =vertico-mode=. The src_emacs-lisp{(describe-function 'savehist-mode)}
Listing [[lst:setup-vertico-mode]] sets up =fido-mode= and =vertico-mode=. 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=. Listing [[lst:prune-file-name-history]] allows to prune
non-existing files from the file name history. BUG: Adding ~eww-history~ or
~register-alist~ to ~savehist-additional-variables~ fails to save the relevant
histories.
=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)}
documentation.
