I'm working on the accessibility of my website, unfortunately the shortcode does not appear to work with tabbed interface so used that do not use a mouse are unable to engage with mp3 files.

For example on this page I have two play buttons, if you navigate the page using tab, you'll notice that you skip straight passed both play buttons.

This will be because you're using a div element to manage play/pause, whereas a Button or A tag would be more suitable.

Is there any chance you would update this in a future release?

Apologies, I meant the Tab key on your keyboard.

Imagine a blind user, they obviously wouldn't use a mouse. Instead they'd  use the Tab key to progressively move through clickable elements within a page with a screen reader explaining what they do based on alt/title tags.

Because your mp3 play button is a div, it's not possible to land on it using keyboard navigation, meaning it's not possible for users to engage with unless they can use a mouse or trackpad.

Head over to https://soundcarrot.com/shows/master-machine/bonus-master-machine-first-appearance/ and press the tab key, you'll see what I mean.

That's a shame, as unfortunately that means any website using your plugin (or themes I guess) is totally inaccessible for blind users and those with mobility issues preventing the use of a mouse/trackpad.

I'm sure I can find and edit the required tag, so no worries there, but I'd urge you to raise this as it's a very small tweak that would radically affect the usability of your tech.
