She has Manager, luckily, so I was able to tell her to use PowerEdit to do this.
1. Go to Pages. Select all your pages and click PowerEdit.
2. In the Information box, select Link Name. Below, select Individual. Click Proceed.
3. Give each page a Link Name that is the text you want to appear in the page link. Save Changes.
4. Select all pages and click PowerEdit. In the Information box, select Name. Below, select Individual. Click Proceed.
5. Give each page a Name that starts with a number. I suggest names like "1: books" and "2: cds" etc. etc. Of course, number them in the order you want the links to display. Save changes.
6. Select all pages and click PowerEdit. In the Layout box, select Display Name? Below, select Global. Click Proceed.
7. Uncheck the Name Toggle. Save Changes.
8. Select all pages and click PowerEdit. In the Layout box, select Order. Below, select Global. Click Proceed.
9. Set Order to Ascending. Save Changes.
10. Select all pages and click PowerEdit. In the Layout box, select Pages Sort Field. Below, select Global. Click Proceed.
11. Set the Page Sort Field to Name. Save Changes.
What you've just done is given each page a "behind-the-scenes" name that is not displayed on the page, but controls where the link to that page shows up in the list of links.
