The Edit menu consists of two menu items. The Copy
  menu item copies a selected portion of text into the
  clipboard.

  The Select All menu item copies the whole of the
  current help topic to the clipboard.

  For further details, select the appropriate menu item
  from the list below.

1  –  Menus Edit Copy

  The Copy menu item in the Edit menu copies the selected
  portion of text into the clipboard.

  This is useful for copying details into another
  application, for example to fill in a text block in a
  paint program, or to insert a detail into a Calendar
  meeting agenda.

  If you want to copy the whole topic, it is easier to
  use the Select All menu item.

2  –  Menus Edit Select

  The Select All menu item in the Edit menu is an easy
  way to select the whole of the current help topic. It
  can then be copied to the clipboard.

  Like Copy, this is useful for copying details into
  another application, for example to fill in a text
  block in a paint program, or to insert a detail into a
  Calendar meeting agenda.
