W: What’s the problem?
M: I can’t figure out how to put the page numbers on. I’ve done everything and they aren’t showing up.
W: Let’s see. Did you press Shift, F-8?
M: Yes, I did that. Then 1 hit P for page and N for number.
W: That’s good. Did you type in the page number where you want the numbering to start?
M: Yes. I typed the number 1.
W: Right. Did you press Enter?
M: Yes.
W: How about F-7 return to the document?
M: I did that. But no number’s showed up on the screen.
W: Unhuh, Did you print it?
M: No, I don’t want to print it until I see the numbers.
W: Well, that’s the problem then. The numbers don’t show up on the screen. But they will be on the printed copy. Let’s try that.
M: Okay. You do it this time, and I’ll watch.
W: Well, I’ll do it if you want, but it would be better if you let me talk you through it.
M: I don’ t know.
W: Really. Once you’ve done it with someone coaching you, it’s easier to do it on your own. Don’t worry. This is my job.
M: Oh, all right. Shift, F-8.
W: Now hit P for page and N for number.
M: And the page number I want to start with which is number 1.
W: Great, just press Enter, then F -7 to return to the document,  and you’re all set to print. Then you’ll see those numbers.
