Rollever for teaching R coding and for defining words in general

This regular expression learning tool is excellent: https://regexr.com

It would be great if Quarto had a way to allow us to explain piece by piece the elements of a sentence or of a complex R expression, just as rolling the mouse over elements of the regexp causes explanatory boxes to pop up.

Yes, I use regex all the time to write my own regexes! Agree that this would be an incredible thing to do for R code. Note that its possible that this could be implemented as an extension: https://quarto.org/docs/extensions/
