binding event on tkinter?

[micoud78 at hotmail.com]

hi,

can anyone tell me how to bind the ctlr-> and ctlr-< event on a text
widget?
it seems that :
  mywidget.bind('<Control-<>', mywidget.mymethod)
or
  mywidget.bind('<Control-Shift-,>', mywidget.mymethod)
(my keyboard is a qwerty one)
does not work.
And the tkinter does not tells about those kind of special binds


thanks for help
