A quibble. When I select hyphens, I can move the lyric line up or down. But I can’t do it when I select a preambular hyphen:
Yes, I’m pretty sure you’ve mentioned this before. It’s awkward to handle this, unfortunately.
Sorry, I did search first! In this case, no skin off my nose. Just reporting. 
Any updates on this, developers? I see what seems to be the same behavior in Dorico 4.3, but it’s hard to know if I’m selecting the right handle.
No, there has been no change in this area. Select a lyric rather than the handle.
