+#### Saner command-line history
+
+If you're anything like me, you're used to going to next and previous items via
+`<c-n>` and `<c-p>` respectively. By default, this also works in the
+command-line and recalls older or more recent command-lines from history.
+
+So far, so good. But `<up>` and `<down>` are even smarter! They recall the
+command-line whose beginning matches the current command-line. E.g. `:echo <up>`
+may change to `:echo "Vim rocks!"`.
+
+Of course I don't want you to reach to the arrow keys, just map it instead:
+
+```viml
+cnoremap <c-n>  <down>
+cnoremap <c-p>  <up>
+```
+
+I depend on this behaviour several times a day.
