... regardless of whatever, with X and xterm and xev
(and possibly the uncanny X-Men as well, tho we have
to look into that), you *are* able to get output that
indicates a distinction between the numerologist
keypad and the bender arrow keys, e.g.:
keycode 83 (keysym 0xff96, KP_Left)
vs.
keycode 113 (keysym 0xff51, Left)
This tells me, in principle there shouldn't be
a problem for 'emacs -nw' to do the same. Why this
doesn't happen is thus due to some implementation
detail or policy: be it a bug, a coincidence, or
a consideration - either in Emacs itself, or in how
Emacs is run in the terminal.
Perhaps someone in this list that is familiar with
just exactly what the '-nw' option does can
enlighten us?
PS. For me, it works with gnome-terminal as well tho
I don't recommend using it all the same.
PPS. Here is the entire xev output:
KeyRelease event, serial 47, synthetic NO, window 0xa00001,
root 0x22d, subw 0x0, time 20703938, (-1,747), root:(0,767),
state 0x0, keycode 83 (keysym 0xff96, KP_Left), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
KeyPress event, serial 47, synthetic NO, window 0xa00001,
root 0x22d, subw 0x0, time 20704914, (-1,747), root:(0,767),
state 0x0, keycode 113 (keysym 0xff51, Left), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
