| The main editable area of CKEditor can be focused thanks to the [`contenteditable`](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Editable_content) DOM attribute. This attribute tells the web browser that a web page element can be edited like any other text field, which also means it must be able to receive focus. | ||

| Each root of the editing view has the `contenteditable` attribute. The editing view uses the {@link module:utils/focustracker~FocusTracker `FocusTracker`} (learn more about {@link framework/guides/architecture/editing-engine#observers view observers}) to track focus in editables by listening to native DOM `focus` and `blur` events coming from them. |

Because you link to view observers, so the thing you're talking about is FocusObserver, not FocusTracker. The engine view definitely uses focus observer.

The guide is fantastic. I think it's by far the best one we have :) I think there's only one thing that I miss – a clear explanation that there's this main editor focus tracker and that all focusable roots are registered here and a list of these (toolbar, editables, etc). And then a word that we consider the editor having focus as long as any of these items have focus. Theoretically most of these is explained in

Haha :D I've had one last "Conclusions" part to read before I wrote the above comment and I can see that it seems to clarify some of those things. Still, I'd have it somewhere earlier too. |

…right way to change the selection.
TBH, I couldn't find any good place to explain it earlier. Do you have any idea where could it be? |
I think you could just add this additional info as another points in the list I mentioned in #552 (comment). |
Done. They only unresolved discussion is #552 (comment). |
