[Edit] menu

Copy
Copies selected text to the clipboard.
Note: Normally, you don't need to use this command, because dragging text automatically copies text to the clipboard (see mouse usage). Use this command to re-copy selected text to the clipboard.
Copy table
Copies selected text to the clipboard. If the copied text consists of words, each space between words is converted to a Tab character. If you copy a table on the screen by using this command, you can paste it into a spread sheet application, like Excel.
