Pro-Tip: Absolute References

When copying a formula down a column, cell references change automatically. To lock a cell reference (make it absolute) so it doesn't shift when copied, use the F4 key.

How to toggle references:
  • 1. Highlight the cell reference in the formula bar (e.g., A1).
  • 2. Press F4 to cycle through lock states:
    $A$1, A$1, $A1
