HOWTO: Expand/collapse records using keyboard

Hi;

Am I wrong or does the report control not support the keyboard for expanding / collapsing tree-like records?
Where do I have to start from to implement this feature if it's actually not supported?
Will this be supported in next 15.0.3 release?

Ok, ABuenger;

Select the first row (click with mouse) then press the right arrow key until the 9th row is selected. Now press the left arrow key once.
From now on the navigation with arrow keys (left/right/up/down) is frozen until another row is selected by mouse.
And in my case I have 3 columns (first and third column is neither editable nor fousable). In this case the keyboard navigation does not work (I can't navigate with left/right arrow keys).

Update: As soon as I call FocusSubItems(TRUE) and the whole row has no focusable item, the navigation stops working.
In my case all parent records have no focusable items.

Fixed and updated sample:

I'll add the text indent property and then attach the updated source to the issue.
