+By default, when you open a Scheme file, @code{guix-devel-mode} will be
+activated (if you don't want it, set @code{guix-devel-activate-mode} to
+nil). This minor mode provides the following key bindings:

+@item C-c . k
+Copy the name of the current Guile module into kill ring
+(@code{guix-devel-copy-module-as-kill}).
+
+@item C-c . u
+Use the current Guile module. Often after opening a Scheme file, you
+want to use a module it defines, so you switch to the Geiser REPL and

+instead (@code{guix-devel-use-module}).
