In the input field, enter a character. If anything shows up, highlight the entry using the arrow keys. Then press Delete. Repeat until everything is gone.

I tried the proposed solution to begin typing and select the name with the arrow keys. It will select one of them, but when I then hit delete it is still there.

Use these steps to remove saved (form) data from a drop-down list:

1. click the (empty) input field on the web page to open the drop-down list
2. highlight an entry in the drop-down list with the mouse or cursor Down key
   do not click the mouse or press the Enter key
3. press the Delete key (on Mac: Shift+Delete) to delete the highlighted entry

It could be possible that AOL stores these entries on the server or in a cookie, so you have to look for such a remember feature.

Thank you very much. The missing data was that I had to use "Shift-Delete" on the Mac to get it to work. I was trying it with just the Delete key and it was deleting letters from the entry box.
