Paste values ...  
This function copies values from one range to another.
Let us take a look at the following example:
We wish to copy values which cells are colored yellow, to a different cell.
Thus, we copy the yellow area and then we choose the destination cell.
At the first click, it will past numeric format formulas (let us remember that Excel does not copy numeric formats whenever it copies a formula).
At the second click, it will paste all formats.
