+Once you've added a few tasks, you can use the **Prefix Selection List** to
+quickly choose a prefix for your next task. This is intended to make creation of
+new tasks easier.
+
+Go ahead, try it out.
+
+Press `a/o/O/I/A` to start adding a new task, and then press `<ctrl+p>`. Choose
+a prefix from the list and press `⏎`.
