org: Catching invisible edits

 
 2.3.3 Catching invisible edits
 ------------------------------
 
 Sometimes you may inadvertently edit an invisible part of the buffer and
 be confused on what has been edited and how to undo the mistake.
 Setting ‘org-catch-invisible-edits’ to non-‘nil’ will help prevent this.
 See the docstring of this option on how Org should catch invisible edits
 and process them.
