    Default Accessability of tree grids with multiple columns

    Hi there,

    I cannot figure out how to expand the tree grid's node with the keyboard if the tree grid has multiple columns and cell selection. If the grid has a single column the 'right arrow' button works fine, but with multiple columns this does not work because I just cycle through the columns. Is there some way to achieve this?
    Examples from Ext JS Kitchen Sink:
    http://examples.sencha.com/extjs/6.0...ink/#tree-grid
    http://examples.sencha.com/extjs/6.0...#filtered-tree
    ...

    Thanks a lot!

    Not sure if it's possible, but perhaps you could listen for the specialkey event to catch right arrow key presses and expand the appropriate node.

    Pocolashon,

    As per WAI-ARIA design pattern for TreeGrid, the keys for expanding and collapsing rows are Ctrl-Left and Ctrl-Right, respectively (⌘-← and
    ⌘-→ in Mac).

    Regards,
    Alex.
