Forward a mail I just sent to linux-console@

Any idea on this? If this problem can be resolved, I pretty sure CUA
can be enabled in console mode, including ssh pts.

Subject: Different scan code behavior in X and console
To: linux-console@vger.kernel.org


Hi there,

Sorry to bother. Not sure whether it is correct to post this question
to the mail list, but can't find a suitable linux console user mail
list for discussing this. If you have good mail list to suggest,
please help me to forward. Thanks!

The question is: I tried to make my emacs have the same key response
on both X and console (ssh pts). However, I can't find scan code for
"Ctrl-PageDown" in console mode. I attached the code for testing the
scan code, and below is different behavior in X and console:

============= X ===========
Press a Key 338   // Just type <PageDown>
Press a Key 27
Press a Key 91
Press a Key 54
Press a Key 59
Press a Key 53
Press a Key 126  // 6-chars for <Ctrl-PageDown>
============ Console =========
Press a Key 338  // Same for <PageDown>
Press a Key         // No response for <Ctrl-PageDown>

Any idea on this? Greatly appreciate your replies, your suggested
readings, and so on!

Best Regards,
Lamu Guo
