Applescript GREP limit scope?

Hi @grahams6813726 , As @brian_p_dts suggests you can set the grep prferences, get the active page and loop through the page’s text frames:

tell application id "com.adobe.indesign"
	set find grep preferences to nothing
	set change grep preferences to nothing
	set find change grep options to nothing
	
	set find what of find grep preferences to "World"
	set change to of change grep preferences to "There"
	
	--get the active page
	set ap to active page of active window
	
	tell active document
		set tf to every text frame of ap
		repeat with x in tf
			change grep of x
		end repeat
	end tell
end tell

You can get every text frame on a page and change grep on those. If you have anchored frames, you could iterate on all page items and change grep on found text frames. Don't know the AS way of writing that; I'm a JSX guy. But the page object has no change grep property as you've discovered.
