The command is black if available; it is dimmed and sometimes reads "Can't
undo" if it cannot be used to reverse your most recent action.
2. If Undo is available, choose it from the Edit menu.
The Undo command reverses your previous action. In some programs, choosing
Undo a second time restores that action. (In some programs, the command name
changes to Redo when it will have this effect.) Check the documentation for
the programs you use to see how Undo works in each of them.
Shortcut for undoing an action: You can use the keyboard shortcut x-Z to
initiate the Undo command.
Saving documents
Saving your work often is the best safeguard against lost data. Macintosh
programs offer several ways to save documents, providing great flexibility in
managing and storing your work.
When you save, you can
- name the document
- save revisions under a new name or in a new location
- save revisions with no change in name or location
- save all or part of a document in the Scrapbook desk accessory, for access
any time
Some programs also give you the option of saving documents in a different
format -- for example, a format that can be recognized by other types of
computers. For more information, refer to your software manuals.
Most saving options use a form of the directory dialog box in which you name
a document and select its storage location.
Saving a new document on the current disk
When you create a new document and save it for the first time, you must name
it.
When a document has not yet been named, a directory dialog box automatically
appears when you choose the Save command. Similar dialog boxes also appear
when you choose the Save As command (another command in a program's File
menu) and when you try to close a file or quit a program without having saved
a new document.
Follow these steps to save and name a document:
1. Choose Save from the program's File menu.
The directory dialog box appears, with a blinking insertion point in the name
box.
2. Type a name for the document.
If you make a typing error, you can use the Delete key to erase backward, or
