A short time ago I lamented that the built-in file handle tie ability in a Tk Text widget was flawed, in that it didn't 'update' automatically (only when idle, so it was useless for seeing what a running task is doing). I figured not too bad, since I plan some fancier stuff for mine anyway.

Well, I added some concept code to my tie class so I can say 

 print "Normal, ok, now $EFFECT marked, and $NORMAL back to normal,\n"
+;

I'm using a simple control char for each command. In my application, a small number of distinct colors are needed (normal, error, warning, etc.). But to make it general, how should I design it? Maybe embedded strings to indicate any named tag for the widget?
