You can keep a history of your interactions within Workbench by recording your interactions with the program(s) in session journals. Note that these journals can record your interactions with Polyflow-based systems, but any of the manual inputs you make within the Polyflow applications will not be recorded. An example of when it might be useful is when you have an existing setup and you are updating the geometry, mesh, or connections between systems.

Session journals are recorded using File → Scripting → Record Journal....

Additionally, you can use the Workbench  File → Scripting → Run Script File... to play back a previously recorded session journal:

For more information about recording and using session journals, as well as reference documentation containing available commands, see the separate Workbench online documentation.
