- Arrowkey nav, jump to next node in direction of arrow
- Enter to select node, then arrows to select port, enter to jump along that port

I like. For the "in direction of arrow bit" there should be a spatial priority thing.

In this case, pressing Right-Arrow while A is focused goes to B

+-------+      +-------+
|       |      |  B    |
|       |      +-------+
|       |
|   A   |
|       |      +-------+
|       |      |  C    |
+-------+      +-------+

In this case, pressing Right-Arrow while A is focused goes to C

+-------+          +-------+
|       |          |  B    |
|       |          +-------+
|       |
|   A   |
|       |      +-------+
|       |      |  C    |
+-------+      +-------+

In this case, going to C isn't as obvious, maybe a certain distance threshold is required before a node is cosidered to be offset far enough on one axis to lose navigation priority?

+-------+       +-------+
|       |       |  B    |
|       |       +-------+
|       |
|   A   |
|       |      +-------+
|       |      |  C    |
+-------+      +-------+

[edit]

And then since B is fully within A's horizontal axis, should it get priority over C here?

+-------+       +-------+
|       |       |  B    |
|       |       +-------+
|       |
|   A   |
|       |
|       |      +-------+
+-------+      |  C    |
               +-------+

Something that I like in Unity 4's inspector is that you have a similar interaction with moving up and down through property drawers, hitting enter to edit that property, then hitting enter to go back to property-nav mode.

I want to be able to move down through properties and then jump to a nearby node quickly. Maybe use a modifier key to distinguish between property navigation and node navigation?

e.g.

• NodeNav := ArrowKeys
• PropertyNav := Ctrl+ArrowKeys

The key is is that properties are not assumed to be listed only vertically, so you can focus property editors within a node, then hitting Enter or some other key while a connection port is focused could focus the node that this port is connected to.
