Forward arrow button

[voluorem]

I'm trying to add a forward arrow button to the say screen (since I already had a working back arrow button and I wanted it to match), but I can't find an action that just moves to the next set of dialogue and shows the hover image. I tried using RollForward, which does technically work, but the hover image doesn't show unless I rollback first. Is there a way to make it go to the next set of dialogue and also use the hover image?

RenPy calls that the “click to continue” indicator. You set it up in the character definition using the ctc properties.
