Hi,
officebutton, excel options, customize, dropdown field change from
popular commands, to macro.
If there is code in your workbook, you will see your macro module listed
below. click the add button in the middle to move it to the right side.
it is now in the quick access toolbar.
if your workbook does not contain any code modules, you will not be able
to see anything below the macro button.
to change the face image of the button, after you have done the above,
there is a modify button near the bottom right. click it and change to
the icons shown as desired.
