I think Nomi wants the box that pops up when you put a macro button on the toolbar. When you click on it, you're asked which macro you want to assign. Here's the steps at the link I gave. See the very last paragraph at the bottom first, and you'll understand.
Step 4: Assign the Macro to a Toolbar Button
Hit Tools-Customize and choose the Commands tab. The following dialog box appears:
Under the Categories (left), scroll down and choose Macros. Click on the smiley icon and drag it up to any location you choose on any toolbar you choose. Your mouse pointer must have a plus sign (+) hanging on it before you lift your finger from the mouse or the icon will not be placed. While dragging, you will see an X hanging on your mouse pointer.
Once your icon is placed on a toolbar, click the Modify Selection button, and various options will appear. The following describes only those options that apply for our purposes here:
Name: Type in the name of the macro as it should appear on your toolbar if you are going to use the text style button (described below).
Reset Button Image: Select this only if you have begun to edit an existing button image and you would like to reset it to the default.
Edit Button Image: Select this option to "draw" your own button image.
Change Button Image: Select this option to change the existing button image to one of your choosing from Office's collection of button images.
Default Style: Clicking this button makes the button on the toolbar show just the icon and no text.
Text Only (always): Clicking this button makes the button on the toolbar show just the text as it is shown in the Name box, which you can change.
Image and Text: Clicking this button makes the button on the toolbar show both the icon and the text.
When the button appears exactly as you would like it to appear on the toolbar, hit the close button on the Customize dialog box.
The first time you hit your new toolbar button, you are asked which macro you want it to run. You'll pick your new macro from the dialog that pops up.
