The comment in #defaultStyleTable says:
"color can be a valid argument to Color class>>colorFrom: , or nil to
use the editor text color.
Multiple emphases can be specified using an array e.g. #(bold italic).
If emphasis is not specified, #normal will be used.
if pixel height is not specified , then the editor font size will be used.
"
If you get into it (i.e., browse sender chains and read some code[*1]),
you'll find that it will ultimately do a #perform: of the symbol on
TextEmphasis so if you look at the class side of TextEmphasis you can
see that valid symbols would be #bold, #italic, #narrow, #normal,
#struckOut, #underlined. And if you need additional ones just implement
the proper method ;-)
[*1] Browse senders of styleTable which gets you into
#initialTextAttributesForPixelHeight: where you can see that
#attributeArrayForColor:emphasis:font: is called for the text emphasis
symbol. Browsing the implementors of
#attributeArrayForColor:emphasis:font: shows that the actual attribute
is created via "TextEmphasis perform: each" which leads you straight to
TextEmphasis and its class methods.
