By default, when the user selects a cell, Excel highlights the row and column by changing the color of the associated row and column headers. This tip shares multiple ways to highlight the row and column in more obvious ways as well as a way to highlight the cell in a specific column in the same row.
The emphasis is on the use of conditional formatting to accomplish the task. The minimal VBA code required to make it work is the same single executable statement for all of the different highlighting options!
