With throw/catch signal events, an in-flow signal event broadcasts a signal, and if there is an active task with a signal event on the task boundary, that event "catches" the signal, and generally follows the exception path.
When you specify signal names in the Properties view for signal events, you can use content assist. This means for example, that if you have entered SIGNAL1 for a throw signal event, when you specify the signal name for the catch signal event you can press Ctrl+Space and the available signal names are displayed from which you can select one.
Use the Map from Signal tab to map from the throw-signal's payload data (listed in its interface tab) to the data associated with the attached user task.See the example in Using Message Event Handlers in Business Processes which demonstrates the use of event handlers and non-cancelling signal events to update work item data
