On the Macintosh: Edit Menu
The Edit menu in most Macintosh programs is almost identical to the one in almost every Windows program. Most of the menu items—Cut, Copy, Paste, and so on—have the same names and keyboard shortcuts as in Windows, except that you use the Command key instead of the Ctrl key.
The commands in the Macintosh Edit menu work exactly as they do in Windows—you can cut, copy, or paste highlighted material in your applications. On the Macintosh, however, you can’t use the Cut, Copy, and Paste commands on Desktop icons themselves, to move for copy actual files to other windows.
For information on the main commands in the Edit menu, Cut, Copy, Paste, and Undo, see their respective entries. Among the other Edit menu items are:
Paste Shortcut. Since the Mac’s Paste command can’t paste a file, there’s no Paste Shortcut command.
Select All. The Select All command (Ctrl-A) in Windows is identical to the Mac’s Select All command (Command-A)—with one exception. In Windows, Select All highlights all the icons in a window. But if you’re editing a file’s name, Select All doesn’t select all the text in the name; the Ctrl-A keyboard shortcut doesn’t work at all. On the Macintosh, Select All highlights text if you’re editing a filename, and highlights all icons in the window if you’re not.
Invert Selection. The Invert Selection command, which highlights all the files in a window that aren’t already selected, has no equivalent on the Macintosh.
