How do I create navigational controls for a canvas layer?

We have a lot of legacy content created in Flash that needs to be converted to HTML5 for iOS devices.

I am testing to see if I can control (pause, play) an animation created in Flash and published to HTML5, which I have now opened in Edge Animate. It plays fine, and I see it in the elements panel as a canvas, I realize I can't edit it, but can I pause it? And then start it again from the same location?

I tried importing and using jCanvas, adding this script to a Pause button that lives on top of the canvas, but it isn't working yet:

$('canvas').stopLayer(0);

What else can I try?

Thanks!
