Edit: Find and Replace (Ctrl+H) dialog is improved to
Search Only Inside Cell Formula checkbox to search formula expression only.
When Search Only Inside Cell Formula checkbox isn’t checked, search is based on display. E.g.
if formula mode is on(formula expression and cell:// linking syntax ), then Find and replace will search the expression and syntax.
if formula mode is off, then Find and replace will search the result value
Include Notes on Find tab searches embedded notes only. No cell notes will be searched.
