To highlight a single icon in preparation for printing, opening, duplicating, or deleting, click the icon once. Both the icon and the name darken in a uniquely OS Xish way.
That much may seem obvious. But most first-time Mac users have no idea how to manipulate more than one icon at a time—an essential survival skill in a graphic interface like the Mac’s.
To highlight multiple files in preparation for moving or copying, use one of these techniques:
Highlight all the icons. To select all the icons in a window, press ⌘-A (the equivalent of the Edit→Select All command).
Highlight several icons by dragging. You can drag diagonally to highlight a group of nearby icons, as shown in Figure 3-2. In a list view, in fact, you don’t even have to drag over the icons themselves—your cursor can touch any part of a file’s row, like its modification date or file size.
If you include a particular icon in your diagonally dragged group by mistake, ⌘-click it to remove it from the selected cluster.

There’s a faster way to do the same thing; see Figure 3-3.
