How to move back and forth between dialogue?

[finnlawrence]

Hello, I'm making a sort of ace attorney style game and something I'm having trouble with is how to make the player able to move back and forth between a section of 'say' statements. I only want to do it in certain sections, the way ace attorney does with testimony, and if possible can this be done without a separate screen?

If anyone can help, thanks in advance!

Ren'Py already have rollback. Is there any reason that was not sufficient? Or that you want to disable it for some part of the game?

I was hoping to disable it for most of the game, and re-enable it only for certain parts.

You could try this:
1. Make a new keymap's key. Move everything from the "rollback" key to this new key.
2. Declare a variable at the game start the indicate whether rollback is allowed.
3. Add a keymap to the say screen which receive the new key and perform action Rollback(). This keymap is only there if the variable let it.
