When one right clicks on some selected text in a field, one has a choice of "Protect selection" (in submenu "Protect terms") that puts "{" before the selection and "}" after it. Perhaps it would be worth to have an opposite action, "Unprotect selection", that would remove all such "protections"? It would be especially convenient when, the imported record has protected words in all caps, and one wants to use, for example, title case.
