From the project editor, you can save either via “Save” or “Save as” option just as you would when working in a text document. You can access these functions via:

Windows/ Linux:
Save: Crtl+S
Save as: Crtl+shift + S

MacOS:
Save: ⌘ + S
Save as: ⌘ + shift + S. .

Note: If you’re editing a project with unsaved changes, if you try to exit the application or return to the home screen, a dialog box will appear to prompt you to save or discard your project.
