I’ve created a timeline that swaps out active / inactive buttons in a menu (the button arrangement for scene one is at button timeline 0 sec., scene two is at button timeline 1 sec., etc.).
I want the timeline to be a persistent symbol to control the menu for each scene. I’m not sure what to select. If I select the keyframes in this timeline, create a symbol and assign the symbol to be persistent, I get a resizable gray object with text about the symbol (why resizable?), but the timeline does not appear in any but the first scene. This is confusing. I don’t need a gray box in front of everything. What does the shape and position of the gray box represent? Is this supposed to be resized and aligned with the menu bar?
The documentation says that a timeline can become a symbol and what it can do, but it does not say how.
