Workspace close/clear event?

I want to capture the event in a viewExtension.
This is where I got that information.

Dynamo API Events

Can anyone explain what each workspacemodel event does in Dynamo? I have been playing with them but I cannot seem to figure out what event triggers them. The descriptions are rather vague too. http://dynamods.github.io/DynamoAPI/Dynamo_Graph_Workspaces/WorkspaceModel/#events RequestNodeCentered CurrentOffsetChanged Cleared (several have a Cleared event but not sure what it is) Note (Added Removed Cleared) Annotation Connector MessageLogged Thanks
