Working with Documents
To save a document, choose File > Save... If you are saving a new document, the program will ask you to specify a name for it and a save destination.
The operating system automatically saves versions of modified documents. Due to this feature, you don't need to save documents during your work. Since the auto save feature has limitations, it is recommended that you periodically save your document manually.
To create a copy of the current version of an open document, choose File > Duplicate. This command doesn't create a new file immediately. You have to save the duplicate manually.
You can save a document as a template so that it can be used later as a basis for new documents. To do this, choose File > Save As Template... For more information, see Using Templates.
In the program Preferences, you can choose how often the program automatically saves a copy of your document. This function is useful for avoiding data loss in case of a power shortage or software problems.
If you have an account at iCloud, you can save your documents to your iCloud storage. The iCloud option is located in the Save and Save As dialogs. This feature is available only if the program was downloaded from App Store.
