I would like to know this too. It's much easier with a mouse (in case you're using a tablet). Camera angle can be key as well!

Nothing like hovering the mouse over repeatedly to find the perfect spot.

Honestly I'll x-drag from the Viewer onto the Null in the Navigator most of the time, but you can scale it up.

Aligning in the nav window is good solution thanks! I don't see where one can scale the selection area of the null. I can scale the length of the locator arms but not their thickness which would allow easier selection.

From what I hear about MotionBuilder it seems like it's more of an exercise in patience?

quite. Its super weird in a lot of areas.

You can increase the size of the null in the object properties, but this won’t make the lines thicker. Alternatively you could create a Marker object which will function exactly the same as a null. If you set it to a hard cross it’ll look like a fat null and be easier to select.

Oh wait, Markus already said this. Missed his reply. You could also use Schematic view instead of Navigator. I find it's more immediate when you're dealing with hierarchies.
