This is a key place in the manual - you find it on the lefthand Sidebar, and it shows you the titles of all the pages (Tiddlers) that are currently opened on your desktop.

"Self-service" chapters

When you are reading content in a tiddler, if you click on an interesting link, you will NOT immediately flick from the material you are reading into this new material... Instead, you will see that the links you click open at the bottom of your "Currently Open" list: it is as if you are "ordering up" the chapter that you want to read as you read. We have set the manual to behave in this way as Feedback suggested that readers struggled to stay on task if they were clicking on lots of links.

Navigating with the Currently Open List

Sometimes you may find you have opened lots of tiddlers (like having loads of 'flashcards' spread around your desk), and the "Currently Open" list helps you manage and navigate around them.

• You can click on any title in this list to jump straight to that tiddler.
• You can close any tiddler in the list by clicking the X next to it.
