Frequently Asked Question
The Mac OS Clipboard is a holding area for the last thing that you cut or copied. That copied item can be text, a picture, a portion of a picture, an object in a drawing program, a column of numbers in a spreadsheet, any icon (except a disk), or just about anything else that can be selected. In other words, the Clipboard is Mac's temporary storage area.
Most of the time, the Clipboard works quietly in the background, but you can ask the Clipboard to reveal itself by choosing Edit→Show Clipboard. This command summons the Clipboard window, which lists the type of item (such as text, picture, or sound) on the Clipboard and a message letting you know whether the item on the Clipboard can be displayed.
As a storage area, the Clipboard’s contents are temporary. Very temporary. When you cut or copy an item, that item remains on the Clipboard only until you cut or copy something else. When you do cut or copy something else, the new item replaces the Clipboard’s contents, and the newcomer remains on the Clipboard until you cut or copy something else.
If the Clipboard is empty or the current document can’t accept what’s on the Clipboard, the Paste command is dimmed. Finally, when nothing is selected, the Cut, Copy, and Clear commands are dimmed. Icons can’t be cut; they can only be copied or pasted. So when an icon is selected, the Cut command is always gray.
