+#+cindex: repeating navigation commands
+When ~repeat-mode~ is turned on, headline motion commands, link and
+block navigation commands by only pressing a single key.  For example,
+instead of typing {{{kbd(C-c C-n)}}} repeatedly, you can just type
+{{{kbd(C-c C-n n n n p u ...)}}} to move to different headlines.  When
+a key not in the map is pressed, it exits ~repeat-mode~ and the
+command corresponding to the key is executed (see the
+[[info:emacs#Repeating][Emacs user manual]] for more details).
+
+By default, the following commands are made repeatable in separate
+keymaps.
+
+~org-navigation-repeat-map~:
+
+| Command                           | Key binding        | Repeat key   |
