Thanks Praneet! It's still early, so I don't have enough users for a clean pattern yet. My bet is keyword match, because it's the most obvious to act on: you see the missing word, you add it. The irony is that formatting traps usually matter more, since a two-column layout can scramble the whole parse, but they feel less urgent than a missing keyword. Going to watch which one people actually fix first and maybe write it up once I have real numbers.
