There are two main ways to assign a shortcut key or button to run a macro in Excel:

1. Using the Macro Options Window:

* Open the Developer tab. (If you don't see it, you might need to enable it. You can find instructions online).
* Click on "Macros" in the Code group.
* This will open a dialog box listing all your available macros.
* Select the macro you want to assign a shortcut key to.
* Click the "Options" button.
* In the "Macro Options" window, you'll see a box labeled "Shortcut key."
* Press the desired shortcut key combination (e.g., Ctrl+A, Alt+Shift+M, etc.) on your keyboard.
* Note: Avoid using shortcut keys already assigned to Excel functions or other programs.
* Click "OK" to save the shortcut key assignment.

2. Assigning a Macro to a Button:

* This method involves creating a button on your worksheet that, when clicked, runs your macro.
* Open the Developer tab (as mentioned above).
* Go to the "Controls" group and click the "Insert" button.
* Choose "Button" from the available control options.
* Click on the worksheet where you want the button to appear.
* A "Assign Macro" window will pop up.
* Select the macro you want to assign to the button and click "OK."
* Now you can click the button on your worksheet to run the macro.

Additional Tips:

* You can right-click on the created button and format it to change its appearance (size, color, etc.).
* Remember that shortcut keys you assign to macros will only work within the Excel application.
