PageUp and PageDown in Webmail go to the next/previous Webmail page rather than scrolling down/up the current page (which may well not fit on the screen). I suppose there is some logic in this, but it doesn't behave like most web pages. Is there a way to change this behavior?
It looks like this is built into Roundcube and there is no setting to override that behavior; it just is what it is. As far as I can tell they added that "feature" in 2010 and it's been there ever since.
I agree, it seems kind of strange. I've never noticed that before, I guess I always use the mousewheel in webmail rather than the keys.
