Usually the arrow keys generate the ANSI sequence which terminal will
understand like a movement, so it is not necessary any dealing for them, the
program can not know if the sequence is generate for a echo key or directly
from the program. If you need really know if the key was pressed then you
need activate the keypad mode where the keys will generate a special code
for each keypad key.
The terminfo capabilities kcub1, kcud1, kcuf1 and kcuu1 are used for this
keypad code, not for the sequence generate in the ansi mode.
