I looked through FAQ/Docs to see if there is any command which may move subtitles up/down but without any success.
Is there such command?
According to this, there is such a function.

But it seems to be undocumented.

Well, thanks for the answer, but it is not what I am looking for.
My problem is to move subtitles up/down on screen, not to switch to next subtitle...
