What I would do...
1. Press Alt+PrintScreen. This copies the current window to the clipboard
(PrintScreen itself copies the entire screen).
2. Open MS PhotoEditor (comes with versions of Office prior to 2003), and
choose Edit - Paste as new image.
3. Use PhotoEditor's Crop tool to crop to just the toolbar I want.
4. Select the toolbar image and copy it to the clipboard (or save it to a
file)
5. Paste it into Word (or use Insert - Picture, if saved to a file).
