i believe that key triggers replaces the normal functionality ,Yes, that is right.
for instance , i've created a text_item with a key down trigger to message('aword') , and i did it with no problems, and in this situation, it does not open the list , it only gets the value of the next record without showing the list .Yes, of course. It works like that in a text item.
and i've a text item t with the key-down trigger and a t-list "t3" when i press the down arrow while i am standing on the "t" to go to the t-list ,nothing happens ,with no errors . why is this happening ?When you use the down-arrow key when cursor is in a tlist, key-down trigger does NOT run. Instead, the down-arrow selects the next choice below the present one in your tlist. But if you are at the last choice, or there is only one choice in your tlist's list of elements, then nothing happens.
