Throughout much of your work in Enterprise Architect, any changes you make are automatically saved when you close the dialog (data entry window) on which you made the changes. In some cases the dialog contains a Save button, which enables you to save your changes and then keep working on the dialog.

If there is no specific dialog, such as when you create a diagram, you can save your work by pressing the [Ctrl]+[S] keyboard keys, or by selecting the Diagram | Save menu option.

Often, Enterprise Architect does not let you close a screen without confirming that you want to save or discard your changes.
