Maybe even a "Press-A-while-facing-to-read" signpost combo? It would look kinda weird if someone was reading a sign that's behind them.
Maybe add a person combo; it's like an eyeball combo, only you can "talk" to it. Or it could be like a signpost only it faces you. Wait, you could fake it by using an eyeball combo, and a signpost.
What about just a plain old "display string" and "display string (press A)" combos?
