Base: Forms: Event properties for Macros

Hi guys

Can someone refer to me to online resources to learn the different event properties in basic for form events?

I see for example that After Updating events have a source and that source has a parent and active connection etc.
But for key press events you cant use that object/property tree. Where can I see a list of objects and their properties and methods?

ok, I upgraded to LO 4.2 now and that has access2base on it.
There I can use events(oEvent).EventType

Thanks JPL!
