Thanks Gary for he explanation, I understand.
I have checked and yes in my terminal, a xterm, is returning the same codes
for both Home and Ctrl-Home, in fact any combination of Home returns always
the same code.
So is there any way so setup a xterm to send to client applicatins keycodes
instead of the ASCII 8bits codes???
thx
