 The use of these gives a notion of "direction" when navigating the menu.

 The downside of supporting transitions is that for these to work, the code should render the screen _first_ then return the new state.
 This ensures there is a good working copy in the buffer before the transition changes the view.
 
-## TODO notes
-
-On settings menu exit:
-
-```
-      OLED::useSecondaryFramebuffer(true);
-      showExitMenuTransition = true;
-
-```
+The code that handles the dispatch will run a new render pass again to get the new buffer contents and then transition between the two for you.
+At the moment scrolling "Up" isn't implemented but the enumeration is there so that its implementation can follow.
