I want to customize the appearance of an icon on the quick access toolbar. The icon I want to change would be associated with a custom macro that I created. I already know how to assign an icon using the "modify" button in the "customize quick access toolbar" screen, but this only lets me pick among existing icons. I would like to edit/create my own custom icon to assign to my macro.

I searched my hard drive for *.ico files but did not recognize any ico files that appear on the quick access toolbar. If I can determine where these files are, I presume I could easly edit one of them using a Paint program or similar.

Thanks in advance for any help.
