Apple Macintosh LC - Manual (Page 29)

The sentence disappears.
2. Close the document by choosing Close from the File menu.
A dialog box appears reminding you to save your document. Don't do it! The
point of this experiment is to see what happens if you do not save your
changes.
3. Click the button labeled No.
The document closes (but you are still in the TeachText application program).
4. Now reopen the document by choosing Open from the File menu.
The familiar dialog box appears.
5. If necessary, click your document "Camping Ad" in the list.
6. Click the button labeled Open.
Your document opens again.
Notice that the last change you made (deleting the first sentence) was not
preserved when you closed the document. That is because you did not save the
document before you closed it.
In order to make sure that work you do is not lost, you must save your
documents. Saving writes the changes you make onto a disk so that the changes
will be there the next time you open the document.
What's Going on Here?
The last few exercises point out two important ideas:
- Deleting is different than cutting.
- Changes are not automatically saved when you close a document.
Deleting versus cutting
The difference between Delete and Cut is simply that when you cut something,
it is stored in the computer's memory (in a place called the Clipboard) so
that you can later paste it back in your document. But when you delete
something, it is simply erased. Since deleted material is not stored on the
computer's Clipboard, you cannot paste it back into your document later. The
only way to retrieve deleted material is to choose the Undo command
immediately after you delete the material.
Closing without saving
You saw in the last few steps that anytime you close a document without first
saving changes to the document, your changes are not retained in the
document. Generally this is unfortunate because work you have done will be
lost.
However, if you decide that you do not want to save the changes you have made
to a document (for example, if you realize that you accidentally opened and
edited a document you did not want to alter), you can restore the document to
