Yes normal save command, from the manual:
4.12 HOW INFORMATION IS HANDLED
When working within a project there is no need to save as all changes are automatically cached on card. Changes made to a project will be remembered even after the machine has been switched off. The only time an operation needs to be carried out is before removing the Compact Flash card. The project should then be synced to the card. For more information about this operation, please see page 30.
There exists a SAVE command for projects though. Once you are content with a project, it is wise to save it. If you continue your work with the project, but are not satisfied with the results, you can then bring back the project to the previously saved state by performing a project RELOAD command.
I italicised the part relevant to what we are talking about.
