+by shell and Eshell).  You can set it up globally with:

+
+Alternatively, you can call the @code{fish-completion-mode} manually or in
+shell/Eshell mode hook.
+
+The package @code{emacs-bash-completion} is an optional dependency: if 
available,
address@hidden can be configured to fall back on bash to further
+try completing.  See @code{fish-completion-fallback-on-bash-p}.")
