Summary: input from numeric pad always dropped when numlock off

Initial Comment:
The behaviour of the direction keys on the numpad is
inconsistent when numlock is turned off. 
Home/End/PgUp/PgDn and the arrow keys work fine in some
applications (gedit), but do not work in Python's idle.
By not work, I mean: input is silently dropped.

How reproducible:
Always

Steps to Reproduce:
1. Turn off numlock.
3. Open gedit, type in garbage, use direction keys on
numpad to move around.
4. Open idle, type in garbage, attempt to use direction
keys on numpad to move around. It fails.    

Actual Results:  Intense frustration for people who
have been using the numeric keypad as direction keys
for decades!

Expected Results:  When numlock is off, the direction
keys on the numpad should function in the same manner
as the dedicated direction keys.

I am reporting this for Python 2.3, but I had exactly
the same problem in Python 2.2.

This problem has also been reported to RedHat, see 

http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=136600.

OK, thanks for the leg work.  I'll take a further look.

My keyboards are IBM Model M SpaceSavers.  I don't
do keypads...  :-)

I posted the "bug" on the Tk list as suggested.  Today I got this:

This is not a bug, but rather just that Tk differentiates 
between the regular arrow up and keypad up on some systems, 
depending on how their system keymaps operate.  The first is 
<Up> and the second is <KP_Up> on Linux, but both are <Up> 
on Windows.  This has always been the case for KP_Enter as 
well.  The fact that Windows doesn't separate these is by 
design, but has also caused people to want them separated 
(see TIP http://www.tcl.tk/cgi-bin/tct/tip/158.html). 
 
IOW, the bindings should be on <Up> and <KP_Up> if they are 
to be considered equivalent in an app.  This is best handled 
by using virtual events (like <<Up>>) and adding the 
specific event names that you want to apply to it.  Please 
filter this back to the other reports.

Would  someone please either reopen this or let me know what my 
next step should be. 
 
Thanks,

1) Who is OP?   
 
2) Is this ball in my court or someone else's?

Yes, if OP wants to pursue it, he should take it up with the

Kurt, as far as I can tell, there is nothing in Tkinter that
gives us any control over this.  If you concur, please mark
this as 3rd party and/or platform specific and close it.

In RedHat bugzilla, this problem was reported for fedora
under x86_64.  I have been having the problem on i386 using
CentOS-3, which is similar to RHEL 3.  So the problem seems
to apply across Linux architectures, but not across
platforms.  It may be a RedHat problem across architectures.
