Move the cursor on the interface

[vincent-lg]

Hi,
Thanks for this tool.
Can we (or could we) handle cursor movement? In the documentation_browser for instance, using the arrow keys do update the right panel and the selected module appears with a right arrow sign (>) before it, but the cursor itself is at the very bottom of the window. Perhaps I'm more sensitive than others to it, because as a screen reader user, it's necessary to move line by line toward the top of the window each time a key is pressed (the screen reader focuses on the system cursor by default). In this kind of situation, it would be great if the system cursor were placed on the selected element.
I see several ways to do it. A "focused" option could be added to the DSL elements, though it might be misleading as only one visible element on the current screen could be focused and this wouldn't allow to handle all situations (for instance, in the documentation browser, we might want the cursor to be on the first character of the title and not on the > sign, nor at the end of the line).
Is that already implemented and I missed it somehow? Is there a current workaround even if it's not implemented?
Thanks again,
Vincent
