Replying to both of your messages.
The site mentions using Enter in place of ctrl-V, but not the behavior of essentially canceling the paste-special operation.
WRT pressing <enter> twice, I am either misunderstanding what you wrote, or the behavior is different in Excel 2007
In Excel 2007:
F1: =A1/A2
Select F1
Copy
Paste Values --> formula bar changes to the Value
Enter --> Value remains in cell
Enter --> selected cell changes to F2; Value remains in F1
F1: =A1/A2
Select F1
Copy
Select F2
Paste Values --> Value appears in formula bar (and cell)
Enter --> Formula now appears in formula bar (and cell)
Enter --> selected cell changes to F3, formula remains in F2
So <enter> acts to negate the Paste Value operation, if and only if the copy is to a cell different from the source cell.
There is a commonality in that <enter> seems to do a simple Paste of what happens to be in the cell at the time <enter> is pressed (and not what is in the cell at the time the Copy operation is executed, which is what I would expect). But doing it in that
manner seems unnecessarily confusing.
