Hi,
I'm not really able to prevent the CTRL+HOME and CTRL+END behavior of the tree as it's part of a 3rd party component library but I was able to add the same behavior when you press HOME and END. So in the end, the tree will do the same in both cases.
I was also able to improve the keyboard navigation in the grid views (dashboard) using Home and End.
Thanks again for the feedback!
