I want to find all characters not 12pt font size. I can find the 12pt..how do I find not 12 pt?
What app is your question about please? So your question can be moved to the right forum.
You can't do that directly.
You'll need to do it in 2 stages.
What you'd need to do is search for all 12pt, and colour it red, say.
Then search for all black text and change it.
Then remove the red.
