We’re using jquery.autocomplete plugin to help autocomplete usernames on a twitter client. Whenever the user types the @ symbol, the script is triggered to help complete the desired username.
Problem is that, even when the @ symbol hasn’t been typed in at all, the UP and DOWN arrow keys (used to navigate the list of potential usernames once the drop script is called) don’t work at all. So if a user is typing a long tweet and attempts to use the UP and DOWN keys to move the cursor around the text, nothing happens. the user then has to use the LEFT and RIGHT keys to move around in the text. This doesn’t happen with ESC or RETURN, which are also used by the script. Only UP and DOWN.
Any idea what could be causing this?
