Allow up-down arrow keys to navigate Outline tree
If you have a highly interactive screen, finding all programmed events and respective actions can be laborious. A small tweak would be to allow the user to click on a component in the Outline tree and then allow "up-down" keystrokes so as to move through all components quickly and see the events-actions for each.
Longer-term, offer an event-centric view,... ie I want to see all events on a screen. When I look at an event THEN identify which component it belongs to.
