I made a "notebook" script in Python and bind CTRL+N as next file. At
the first time it works well, but then it stops. I found, that I have to
release CTRL, when using this second time. Is there any solution so I do
not have to release CTRL and just keep pressing N,N,N,....
Thanks a lot

Using Python 2.3 under W2k. 3 2140
The following program just fine for me, printing "Control-N"
multiple times without the need to release and re-press control each
time:
from Tkinter import Tk
t = Tk()
def puts(s): print s
t.bind("<Key-Control_L>", lambda e: puts("Control"))
t.bind("<Key-Control_R>", lambda e: puts("Control"))
t.bind("<KeyRelease-Control_L>", lambda e: puts("Released Control"))
t.bind("<KeyRelease-Control_R>", lambda e: puts("Released Control"))
t.bind("<Control-n>", lambda e: puts("Control-N"))
t.mainloop()
Your problem must be because you've done something more complicated than
you've told us. For instance, if your binding for <Control-n> creates
or destroys widgets, moves the input focus, etc., maybe something bad is
happening.

Solved.- I must have old documentation, I used '<Control_L>n'.
Thank you.

Aha!
The first argument to bind can be a sequence of events, which would
explain exactly the behavior you saw. This *can* be useful (it's in
effect how double-click works) but it can also do something different
than what you want.
