Change selection element by arrows


I need to manage my diagram by hot keys.
Arrows - jump selection from one node to other
Tab - create new child node for selection node

How can I do this using GoJS ?

P.S. I looked at the theme of the forum, but not found a solution.
Current hotkeys do not solve problems.

For changing selection via arrow keys, use and set the DrawCommandHandler.arrowKeyBehavior property to “select”.

As a demo, try and choose Options | Arrow Keys >> Select.

To handle the TAB key, you can override CommandHandler.doKeyDown, as documented in and . The extensions/DrawCommandHandler.js class already overrides that method to handle the arrow keys.
