You can remove tags from notes when they are no longer necessary. Removing note tags is useful if you frequently search by tagged notes and only want to see notes with tags that are current.
Do one of the following:
To remove a single note tag, right-click it on the page, and then click Remove Tag on the shortcut menu.
To remove multiple note tags, place the pointer anywhere in the text containing the tags that you want to remove and then press CTRL+0 (ZERO).
