This question cries out for more detail: What software are you talking about? Microsoft Word? Some other word processor? What do you mean about “highlighting … for the purpose of pasting”? Highlighting is applied to text in the document (in Word and most other word processors) and then left there as a visual aid to readers. “For copying” means “selecting” the text, and copying to a clipboard or directly to another application. And Ctrl-F is used (in Word) to “find” text or formatting in the document. So I’m at sea here. It’s hard to know exactly what you mean by this question. It would probably also be possible to set up a MS Word style or macro that would apply certain formatting to “every other paragraph”. But again, I’m just guessing right now.
