Re: Text folding of text

Yes, it is possible, though you have to do a lot of the work yourself. You
can actually intercept the low level text insertions and deletions that
happen as a result of the built-in bindings, and allow or reject the
insertions based on whatever criteria you want.

You can, for example, check the tags surrounding the insertion point when
text is inserted. If you have a tag such as "readonly", you can prevent the
insertion from happening.

Here's a solution that illustrates the technique:
