-A few other useful commands while viewing a thread. Press 'd' to
-toggle a detailed header for a message. If you've scrolled too far to
-the right, press '[' to jump all the way to the left. Finally, you can
-press 'n' and 'p' to jump forward and backward between open messages,
-aligning the display as necessary.
+Other useful keyboard commands when viewing a thread are: 'n' and 'p'
+to jump to the next and previous open messages, 'h' to toggle the
+detailed headers for the current message, and enter to expand or
+collapse the current message (when it's on a text region). Enter and
+'n' in combination are useful for scanning through a thread---press
+enter to close the current message and jump to the next open one, and
+'n' to keep it open and jump. If the buffer is misaligned with a
+message, you can press 'z' to highlight it.

+This is a lot to remember, but you can always hit '?' to see the full
+list of keyboard commands at any point. There's a lot of useful stuff
+in there---once you learn some, try out some of the others!
