To edit a passage, you can either double-click it on the story map or select it, then choose Edit Passage from the Story menu. (You can open several passages for editing this way.)

The editor window has three main fields: the title of the passage, any tags that it has, and the body text. As you make changes here, the story map will update itself automatically. Close the window when you're done working.

The editor window's Passage menu contains a list of passages that the one you're editing link to (the Outgoing Links submenu), other passages that link to this one (Incoming Links), and links from this passage that don't have matching passages (Broken Links). Selecting a passage title from these menus will open it if it already exists, or create a new passage with the appropriate title if it doesn't.

To concentrate just on a passage's text, choose View Fullscreen from the Passage menu. In the fullscreen view, press the Escape key to close the passage and return to the story map, or press F12 to switch back to the windowed view.
