Copying a Formula from a Cell While Keeping the Absolute Reference or Relative Reference

Avoid the nightmare of pressing <F4> multiple times when coping and pasting formulas.
To copy/paste a Formula without changing the Absolute or Relative references:

Option 1: Select a cell under the cell containing a formula and press <Ctrl+ ’>.
Option 2: Copy and paste the formula from the Formula Bar to a cell, instead of from a cell to another cell.
Example, cell C12 contains a formula:
1.  Select the formula string in the Formula Bar and press <Ctrl+C> to copy it.
2.  Leave the Formula Bar by clicking the Enter or Cancel icons to the left of the fx on the Formula Bar.
3.  Select another cell and press <Ctrl+V>.
