DRC helps

Two ideas:

1) Simple:   interaction bar (F9):  after an error is chosen, you should be able to

move up and down the list using the up/down arrow buttons on the keyboard

2) harder: when an error is chosen, the two components involved should highlight.

--big help since the interaction bar only shows coordinates, not component references.  alternately when a coord pair is chosen in the interaction bar, that could cause the compoents to highlight.
