The primary mapping file of a flow (see Mapping files) is created automatically the first time that you save the flow. You can save a flow in two contexts:
In the host editor, you can save a terminal flow that you have just
recorded or that you have added to or modified in the host editor by clicking
the Save Flow
icon (see Saving a flow).
In the flow editor, you can save a terminal or nonterminal flow by pressing Ctrl-S.
