+This patch adds a few changes to moving between threads:\r
+\r
+- It supports 'scrolloff' so that if you have this set it will move the\r
+  buffer and cursor so the next/prev email starts at the top of the\r
+  screen.\r
+- It adds the ability to use shift-tab to go to the previous msg in\r
+  the thread.\r
