Back button/link is marked as external link

I recently found that external-link also works for revealjs, which is great!

In my revealjs presentations, in many cases I find it very useful to have a 'Back' button (actually a link that simulates the back button of the browser). I use it like this:

[Go back](javascript:history.back())

It works perfectly. The problem is that now that I use external-link, the 'back button' gets marked as an external link, and becomes useless. I tried to use

link-external-filter: ^javascript:history\.back\(\)$ (I checked in https://regex101.com/ that the regex works), but it is still recognized as external. Is there a way to avoid this? Am I missing something?

Note that I use the presentations in full screen, so a link is very handy (as opposed to using the browser's button)

Thanks a lot

This is an 'extra' slide, to be visited (maybe) once, and then go back to continue the explanation.

[Go back](javascript:history.back())

As you are creating the link yourself, the easiest approach is to add .no-external class to your link.

Yes! It works!

For reference, this is how I use it now:

[Go back](javascript:history.back()){.no-external}

Thank you!!
