Thanks for the suggestion, but this is not really what I am looking for. 
I just need to find strings in a Text widget that starts with http:// or 
ftp:// and change the color of them to blue and underlined. I tried 
checking the IDLE source since the IDLE editor does color markup, but
it was too complex to figure out how to translate this into my little
problem. Does anyone have any other suggestions?
