Undo

This button is available when one or more actions that can be undone have occurred.  A tooltip advises of the next action to be undone.  Undoing an action may automatically trigger a refresh of the Interaction Designer (if appropriate).  The button is disabled when an activity's configuration panel is shown.  The history of the undoable actions undertaken within the current Interaction Designer instance is cleared when Save or Save As is invoked.  The history is also lost when the Interaction Designer is closed.  You can click Ctrl-Z to undo the most recent action.  File metadata changes are not added to the history.  You cannot make changes using Undo to an executing workflow (an advisory message is shown when you attempt to do so).
