It seems to work on non-merged clips. And within the sequence the up/down keys work as exprected. But in the source window, with a merged clip (at least that seems to be the problem) the up/down arrows only take you to the beginning or end of the clip.

I'm amending this after further investigation. In an un-merged clip, the up/down keys do snap you to in/out points in the source monitor. But they fail to do so in a merged clip. In the sequence - the keys also fail to snap to in/out points.
