I'm not sure @Daniel read the whole post

He is, in fact, correct when he says about the swipe functionality. Hype has 2 areas where swiping can be used.
On a scene basis and on a symbol basis.
Using a symbol as a control has an added bonus of being able to resize the "swipe(able)" area.

But, if I'm understanding right then you want to go back to any of the 6 scenes from scene 7. For this to work then you would have to run a function when the button is pressed to go to scene 7 that records the actual scene you came from. Something like:

hypeDocument.customData.sceneVisited = hypeDocument.currentSceneName();

Then on the swipe action you can add another function that does:

hypeDocument.showSceneNamed(hypeDocument.customData.sceneVisited, optionalTransition, optionalDuration)

Ah, right you are. Here's a little script for doing this:

Create a 'Back' button to transition to the last-visited scene

First, on all scenes where you want to remember visits, add this JS function to run ‘On Scene Unload’: window.lastHypeSceneName = hypeDocument.currentSceneName(); To create your back button which will look at the last ‘Unloaded’ scene, run this function when the button is clicked: if (window.lastHypeSceneName == …
