Unfortunately it's true, Zuki. I know some learn by pressing buttons, messing about in general, etc., and that's fine, but even reading through a quick start guide for the first forty pages or so has its benefits.

Nobody is expected to wade through the thousand or so pages of a Korg manual, though there's always the masochists :), but you can find questions on any forum that you just know can be answered by spending a bit of time reading.
