How to sort on keydown

[dunbarx at aol.com]

I don't think an option menu responds well to keypresses, whether or not the user has clicked there or not. I don't see any messages sent at all.


I loaded one with a few lines, "A" in the first, "B" in the second, etc.When I clicked in the menu, displaying the contents, and then trying a keypress that corresponded with one of the letters, I got odd behavior. Sometimes it seemed to work, mostly not.



Anyone know if I am right about this?


If so, you will need to build your own control, easy and fun to do.

Chris, 

I did away with the drop down (which was not really a true
drop down since the revlet player cannot scroll drop down boxes in most
browsers), and switched to a option box instead. 

How would I do the
same thing (user clicks the option box and then presses say, the 'm" key
for March?

wrong. How do I make it right? (I want the drop down list to end up on
the letter of what the user pressed on keydown, so if they pressed 'd'
or 'D' I want "December" to become highlighted. Thanks everyone. Mike
