cfselect bind to keypress and onChange?

Here's a quickie (I think):

I want to bind a cfdiv to a cfselect. I want the div to refresh whenever the cfselect value changes, whether the change is caused by a mouse select or a keyboard. The default action for binding the div to the cfselect seems to be onChange, which (at least in Firefox 2) only refreshes on a mouse click; changing it to keypress only refreshes it on (surprise) using the keyboard to change the value.

What's the easiest way to get it to refresh regardless of how the cfselect value is changed?
