Q: How do I delete a note in facebook?
A: Although not intuitive, this is easy to do.

Type Notes into the Search field at the top OR start with your home page (In the news feed list on the left side, click on More, if you do not immediately see ‘Notes’). You may also be able to access notes via a button on your profile, if you have set it up to display that way.

Click on the Note you want to delete.

Click on the Edit button.
Click on Delete.

Do you want to delete? (Yes, right? If not cancel)
