"events" in wpf - 3 meanings

In WPF, the "event" word takes on multiple meanings. Know the subtle differences.

1) CLR event -- used extensively in INPC. These events are generated by code, not user actions. Here "event" has the unique dotnet meaning. In other GUI systems (like swing), events are also generated from code, such as table change event after you add a row.

2) UI event from keyboard/mouse -- the traditional GUI events, implemented (in WPF) with the CLR event + other things. These events have a hardware flavor.

3) routed (bubble/tunnel) event -- a special type of UI events?
