no way to activate "Show Example" using keyboard navigation

[michaelficarra]

I can't figure out how someone navigating only via keyboard (or I'm assuming screen reader) would show or hide the examples. You can't tab to it since it's just a <div>, and even if you could, it can't be activated with the keyboard. I think this will cause accessibility issues.

This may be addressed by replacing the "show example" feature with something else, as in #105.

Hi @michaelficarra -- thanks for pointing this out, this is a regression
