Workflow Designer: What properties appear in the Properties pane when activities are multi-selected?

When multiple activities are selected in the Workflow Designer surface with ctrl+click, it's not immediately obvious which properties appear in the Properties pane, and can be set on multiple activities at a time. When activites are multi-selected, the following properties appear in the Properties pane:

  • Properties that have a common name across all the selected activities
  • Properties that are of type String or a value type.
