Adding a comment/instruction to a command button in Excel using VBA programming

1. Right-click on the command button and select "View Code". This will open the VBA editor.
2. In the VBA editor, find the code for the command button. It should look something like this:
   
   
   Formula:

   Private Sub CommandButton1_Click()
    'Insert your code here
End Sub 

3. To add a comment/instruction, simply type a single quote (') before the text you want to add. For example:
   
   
   Formula:

   Private Sub CommandButton1_Click()
    'This is a comment that will appear when the cursor is placed on the button
    'Insert your code here
End Sub 

4. Save your changes and close the VBA editor.
   

Now, when you hover your cursor over the command button, the comment/instruction you added will appear as a tooltip. Note that the comment will not appear when the button is clicked, as it is only meant to provide additional information to the user.
