I don't know if Tk supports this or not. I guess it just made since to me that it should. If you can bind events to a tag then why not a tag inside a text widget. The actual bind itself works. donothing() is called, the problem is that after donothing() is called and I return "break", Tk continues to insert the text entered. I am just try to lock down one particular part of a text line while leaving the rest of the line, which has a different tag, alone.
