fontifying a pattern in a Tkinter Text widget

[captainkoala at gmail.com]

Hi, I'm writing a program which needs to change various format features
of a specific pattern ("remote_user" for example) withing a Text
widget. This pattern could potentially be anywhere within the widget.

I'm unsure of how to implement the various tag methods, so a little
push in the right direction would be greatly appreciated. Thanks
