My understanding is that you would have to (with code in your button) do 
the following.

Get the selected text with
buffer = getStream(RichTextField, StreamRTF).
Modify it to change various attributes (see below).
Put the text back in the control with putstream(RichTextField, 
StreamRTF, buffer).

To change the attributes of the text, you would have to learn up on RTF.

As an example, the following will display the word 'Euphoria' in plain 
text then in bold text on a new line:

=====================================
{\rtf1\ansi\deff0
{\fonttbl{\f0 Times New Roman;}
}
\f0 Euphoria\par
\b \f0 Euphoria
}
=====================================
The only change is the '\b' to make it bold, but it's the placement that 
is the key.

To test it, copy the file to a text editor; save it with a filetype of 
.rtf; double-click, and it should open in Word.
