Didn't know about the term (and the functionality) "char-folding". If
that's somehow "official" or "standard", let's keep it. BTW, is this
implemented in other editors?  How do they call that functionality?

No, the question is: where to put those "toggles"?  In the prompt, in
the modeline or nowhere?

Best regards,
  Seb
