Use Paste (or press Shift+Ins) to copy a block of text from
the Clipboard to any point in the active window.
 
An insertion point can be defined by:
  ■ Highlighted text; it is deleted and the contents of the
    Clipboard copied in its place.
  ■ The cursor position if no text is highlighted. Then:
      - Less than one line of text is copied to the left
        of the cursor
      - More than one line is copied above the cursor
