FInd and Replace in Pages

The Pages Find and Replace tool is quite obtuse, and has no means to focus on font attributes such as italic.

One could construct an AppleScript to find all occurrences of a Pages italic font and replace it with the same or different font attribute. Open. your Pages document with the italic text you want to fix. Copy and paste the following script into the Script Editor. Edit the font(s) as needed, and then click Run.

-- change all body text matching specific font attributes to another font
-- Refer to Font Book for the specific font name
-- Caveat: You better be using true black text, otherwise {0,0,0} will not match

tell application "Pages"
	tell body text of front document
		
		if its font is "Verdana-italic" and its size is 12 and its color is {0, 0, 0} then
			set its font to "Helvetica"
			set its color to "blue"
			set its size to 14
		end if
		
	end tell
end tell

If the script does what you need, don't forget to save the Pages document, though autosave should handle it.
