Customization of TreeGrid KeyTraversal

I have a tree grid with a single Column, used as a tree.

In can traverse through my tree using ARROW_UP / ARROW_DOWN keys, and select leafs nodes or toggle expand/collapse status for inner nodes with SPACE.
Can these default key-bindings be customized?


There is an enhancement ticket about it here:

I don’t know an easy solution to customize it and transform the Treegrid to a “Tree”. (with all the keyboard navigation).

What is your need for the tree component? Do you need the lazy loading or is it a “small” tree?
