-;; `yas-extra-modes'
-;;
-;; A local variable that you can set in a hook to override
-;; snippet-lookup based on major mode. It is a list of
-;; symbols that correspond to subdirectories of
-;; `yas-snippet-dirs' and is used for deciding which
-;; snippets to consider for the active buffer.
;;
;; Major commands are:
;;
;;
;; Prompts you for a directory hierarchy of snippets to load.
;;
+;; M-x yas-activate-extra-mode
+;;
+;; Prompts you for an extra mode to add snippets for in the
+;; current buffer.
+;;
;; M-x yas-insert-snippet
;;
;; Prompts you for possible snippet expansion if that is
under the menu \"Yasnippet\".
