KEYBOARD '{ALT+DNARROW}' is THE one that works, but you cannot have any code after the command for some reason, that's what at least the results of my tests were.

Try to have only the KEYBOARD '{ALT+DNARROW}' on the gotfocus event of your list. Another reason could be that you may have code on the WHEN event; then again, your KEYB command will be bypassed by any subsequent commands you may have elsewhere.
