I’m not trying to filter user input. I’m trying to trap certain navigation-related keystrokes. I am trying to implement a relatively simple generic auto-complete that allows me to customize the query used to generate the autocomplete list. I’m displaying a listbox under the field the user types in, and filtering the arrow keys to navigate the list. The idea is for the user to type a couple letters, down arrow a couple times to the choice they want, and hit return to select it. The arrow keys can be detected in On Before Keystroke, and that part works fine. The return/enter keys cannot be detected that way. It’s frustrating to have to think about the hassle of managing the choice list in another window just because On Before Keystroke doesn’t detect certain keystrokes.
