A family of Microsoft word processing software products for creating web, email, and print documents.
Assuming that the numbering is coming from the heading style itself and has not been added to the TOC 3 style:
- Place the insertion point in a Heading 1 paragraph.
- Click the Multilevel List button in the Paragraph group on the Home tab and select Define New Multilevel List. This should open the Define New Multilevel List dialog with your list (linked to your headings) selected.
- Select Level 3 and click Font...
- In the Font dialog, all the boxes (Font, Font style, and Size) should be empty. If anything is selected, then clear the boxes and click OK.
- I have found that if Bold has been selected, then, even if the boxes are cleared and OK clicked, the number will still be bold. So return to the Font dialog and select Regular, then click OK. If you then return to the dialog, you'll find that the boxes are empty, and this does remove the bolding from the number.
If the numbering has been applied to the TOC 3 style rather than Heading 3, then you'll need to use this procedure for that style instead.
