 ** What's New
+- Use your mouse to hover over commands and the docstring will be displayed in
+  the echo area or a tooltip, depending on whether or not you're using
+  =tooltip-mode=.
 - The function =which-key-show-top-level= was implemented by @iqbalansari
   (thanks!) to show top-level key bindings (those not behind a prefix). You can
   use =M-x which-key-show-top-level= to try it and bind it to a key if you like.
