>>I've got a special quickfill combobox based on the quickfill combo in "1001 Things ...". However, in our situation, no valid entries can begin with spaces. So, I'd like to make the combobox work like a dropdown list when the spacebar is pressed (i.e. opens/displays the dropdown list).

>>I tried trapping the spacebar in the interactivechange event and then calling this.DropClick. That seemed to have no effect.

Sure you can. In your ComboBox.KeyPress:
LPARAMETERS nKeyCode, nShiftAltCtrl
IF nKeyCode=32 AND nShiftAltCtrl=0
NODEFAULT
KEYBOARD '{ALT+DNARROW}' PLAIN CLEAR
