+## Change Heading Levels
+
+The workflow provides hotkeys that allow you easily change the heading level of a line in your note. A hotkey is simply a combination of keys that you press together in order to perform an action. These hotkeys are specific to The Archive and will only work if The Archive is the front most application and in focus.
+
+To use these hotkeys, click on the line in your note that you wish to change and then press the hotkey.
+
+> **Note:** These hotkeys use the **⇧⌘L** keyboard shortcut that is provided by The Archive to select the current line of text. If you have mapped this keyboard shortcut to something else, then these hotkeys will not work.
