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

refresh();
int key = wgetch(_window);
printw("%d \n", key);
}
endwin();
return 0;
