Hi Kevin,

The following sample code looks for uppercase characters 'UT' before any of specified delimiters. If found, it is set to bold and color changed to red. It's not exactly what you're looking for but it should get you started

* SelChange event of RTF control
lcDelimiters = ",. "
* SelLength = 0 - Nothing selected
IF THIS.SelLength = 0 AND This.SelStart >= 3 ;
		AND (SUBSTR(This.text, This.SelStart,1) $ lcDelimiters) ;
		AND SUBSTR(This.text, This.SelStart-2, 2) = "UT"	 
	* Save Current settings for selected text	
	lnSelStart     = This.SelStart
	lnSelLength    = This.SelLength
	lnSelColor 	   = This.SelColor
	* Select UT and make it bold and red
	This.SelStart  = This.SelStart - 3
	This.SelLength = 2
	This.SelBold   = .T.
	This.SelColor  = RGB(255,0,0)
	* Restore settings for selected text
	This.SelStart  = lnSelStart 
	This.SelLength = lnSelLength 
	This.SelColor  = lnSelColor
	This.SelBold   = .F.
ENDIF
