So on my web application I have a floating button for back to top that's visible to users after they scroll down the page from the top.
I was thinking whether I should consider attempting crafting the html in such a way that a screen reader would be able to read it and interact with it. My next thought, this seems like a feature that would already be built into the screen reader and that I have no need to outright duplicate it.
Do screen readers commonly have a simple method for executing back to top?
I don't try to explicitly duplicate functionality provided by the browser, e.g. I would never create a "back button" that mirrors the browser back button. (Sadly I've seen many many applications do this)
