Might be a stupid question, but i rather ask once too often than regret it:
Does Sunlight damage the keyboard?
Not with a good sun block.
Seriously though; by damage do you mean the exterior or the interior? The honest answer would be yes and maybe.
Consider the fact that the Sun is setting the planet on fire and I think it's a strong yes - as anything seems possible.
Just put a cover such as a towel over it when not in use and it will be fine.
