newbie question regarding combo box events

[Arcifus <faraz javanet com>]

Hello,
I'm trying to catch a signal generated by a combo box when its selected value
changes, both by mouse drop down selection and using the keyboard cursors. I
can't seem to find a relevant event or a mask for an event box that would
generate this value change signal. Any help would be great! 

Also...is there searchable archive for this list on the web?  So i don't have
to repeat questions =)

thanke,
