Copies the cell(s) currently selected and places them on the clipboard ready to be pasted into another part of the workbook or into another application, e.g. Word. When 'pasted into their final destination, the cells will be 'copied' in their new location and still remain in the original one. As with 'cut', caution should be taken within Excel as it maintains it's own clipboard which is very 'fragile' and can be cleared by simply pressing the 'esc' key for example.  You can tell when Excel still has it's clipboard retained as the selection of cell(s) will have a moving dotted line around it, showing you that Excel is in 'Cut/Copy mode'.
