+This introduces notmuch-jump, which is like a user-friendly,\r
+user-configurable global prefix map for saved searches. This provides\r
+a non-modal and much faster way to access saved searches than\r
+notmuch-hello.\r
+\r
+A user configures shortcut keys in notmuch-saved-searches, which are\r
+immediately accessible from anywhere in Notmuch under the "j" key (for\r
+"jump"). When the user hits "j", the minibuffer immediately shows a\r
+helpful table of bindings reminiscent of a completions buffer.\r
+\r
+This code is a combination of work from myself (originally,\r
+"notmuch-go"), David Edmondson, and modifications from Mark Walters.\r
