What role and interaction for Code/Plain in demo portal?

I'm working on FLUID-3728, which aims to improve the accessibility of the demo portal through proper ARIA, etc. I'm struggling with the current affordance for switching between the colourized code view and the plain text view on the right side of the pages. I'm hoping the community can help me with some input.

As an example, you can look at

(Note: The portal on this nightly build has not yet been modified with any improvements, so current ARIA and keyboard interactions are not yet "right.")

On the right side of the page are some tabs, one for each of the files used in the demo (html, css, js). Below the tabs (visually "inside" the tab) are two pieces of text: "Code View" and "Plain Text." Clicking on either of these pieces of text with the mouse will switch the display below it between the colourized version and the plain text version.

I'm trying to figure out what would be the proper ARIA role and keyboard interaction for these two options. Are they radio buttons? A toggle button? (Does ARIA even have a specific role for toggle buttons?) Are they tabs (within a tab)? just plain links that activate something?

Any thoughts would be appreciated.
