I found some Excel spreadsheets that were created by other users.
In one workbook the creator used a text box & drawing tools to create
fancy 3D text with stripes on the letters. Does anyone know which
option(s) draw diagonal stripes on letters?

I've tried highlighting the text, right-clicked, and looked at "Format
Text Effects" and "Format Shape". I've also looked at "Shape Fill"
and "Texture", but I can't find out how this text effect was created.

Is there a good way to find out what effects have been applied to
text inside a text box?
