Draws tracer arrows to the active cell from formulas that depend on values in the active cell.
The area of all cells that are used together with the active cell in a formula is highlighted by a blue frame.
This function works per level. For instance, if one level of traces has already been activated to show the precedents (or dependents), then you would see the next dependency level by activating the Trace function again.
