The Create Margin Note command allows you to remove all links associated with a specific margin note.
1. Place your cursor anywhere in the margin note cell you wish to modify.
2. Click the Margin Note button on the Doc-To-Help toolbar.
3. Select Clear Definition Links from the drop-down menu.
Doc-To-Help removes all links that are associated with that margin note.
Alternatively, you can perform the same steps with the Edit|Margin Note menu command.
