This is how to do Alt + M P on Mac in Excel with Accelerator Keys, the native ribbon and alt key shortcut solution for Mac users who get more done with Excel.
Alt + M P is the Excel trace precedents shortcut. It shows arrows from cells that feed into the selected formula, helping you understand where a formula gets its input values. This is one of the most important auditing tools in Excel for tracking down formula errors and understanding complex spreadsheet models.
When you press Alt + M P, Excel draws blue trace precedents arrows pointing from the source cells (precedents) to the active cell. Each time you press the shortcut again, it traces one more level back through the formula chain.
Without Accelerator Keys, tracing precedents on Mac Excel requires navigating the ribbon manually:
With Accelerator Keys, you can use the same Excel trace precedents keyboard shortcut (Alt + M P) that works on Windows — just press Option → M → P. This is far faster when auditing complex financial models or debugging formulas.
