I have a dropdown control that has yes/no options. Using the dropdown control, when a user presses the [down] key the first option is set as the value of the control. Since I need a set of actions to run that dynamically alter the current form for each value, I do not want the form to change with each stroke of the [down]/[up] keys. I want to either:
1. Prevent any [down]/[up] key stroke in this control, or
2. Change the nature of the [up]/[down] key to act as if the [ALT]-[down] key has been pressed.
