Frame 9 keystrokes for entering Paragraph and Character Tags

I have been using the F9 and F8 keystrokes for entering paragraph and character tags, respectively, for 25 years. I just upgarde to Frame 9, and suddenly they behave differently. Instead of being able to type the first few characters of the tag name and pressing Enter to select the tag, you can now only type the first letter and to get to the next tag in the list that starts with the same letter, you type the letter again. Furthermore, if there is only one tag with the letter you type, it automatically selects it without requiring you type press Enter, which might seem like a feature except if you're used to pressing Enter.

Does anyone know if there is a way to go back to the way it was?
