When using command links, all characters up to the first new line character in AddButton's Text argument will be treated as the command link's main text, and the remainder will be treated as the command link's note text.

But in vb, using vbNewLine in the text argument of AddButton will cause a big blank space between the main part of the caption and the description. Using vbCr will not be interpreted as a new line (my first guess), so all of the text will appear in the larger caption font. It turns out the correct choice of constants is vbLf, so I think the documentation should reflect this.
