in reply to right to left Tk text widget

Okay, I think this will satisfy your needs. Backspace and delete still work in their standard left-to-right fashion, but otherwise I don't think there will be any problems.

    Thanks for the code. It is pretty much what I am looking for. I modified it to 1) have only 1 line of text (because they will copy/paste), 2) have a simple menu, and 3) use an Udru font.
