Saving Changes to a Document
Now you want to save the changes you've made to your letter. So far the
changes are in the computer's memory, but if there were a power interruption
right now your changes would be lost. (The original version of the document
is protected because you've already saved it on a disk.)
Important: Power interruptions are rare, but -- as many people have
discovered the hard way -- they can destroy hours of work. You can protect
your documents by saving them often.
Save your edited document now.
-Choose Save from the File menu.
This time you don't see a directory dialog box when you choose Save. The
computer simply saves any changes made to your document since the last time
you saved, without changing either the name of the document or its location.
By choosing Save often, you'll never lose more than a few minutes of work if
a power interruption occurs.
Closing Documents
In an earlier section of this chapter you saw that opening a document
automatically opens the program that created it. However, closing a document
does not automatically close the program. This makes it possible to continue
working in that program if you want to, without returning to the desktop
first.
You can see how this works by closing the document you just saved.
-Choose Close from the File menu.
The document disappears.
What appears on the screen at this point looks something like the desktop you
saw when you were working in the Finder (the program that lets you organize
and work with your icons), but it isn't.
