+Alternatively, you can call the @code{fish-completion-mode} manually or in shell /

+
+The package @code{emacs-bash-completion} is an optional dependency: if available,
+@code{fish-completion-complete} can be configured to fall back on bash to further
+try completing.  See @code{fish-completion-fallback-on-bash-p}.")
