Editor: make it possible to modify non-word text #461
Description
Right now, once you've created a readalong, you can still fix typos in words using the Audio Toolbar in the Editor, but if you have mistakes in the non-word text, like punctuation or whatnot, there is not way to fix it.
We should provide a mechanism in the Editor to modify the text of non-word elements, i.e., the text between or around word elements.
