My keyboard does not have a Fn key, nor a number pad. But I would like to input lots of number with a number pad layout. I wonder if there is an application, which can change some letters, say, 890-iop-kl;
as a number pad when I activate the option.
I use Debian Jessie system. It will be better if the function is realized by command-line like things so that I could extend it to what I want.
Thanks very much.

. I know I've seen a question about that too but can't seem to find it right now. Maybe it is over on Unix & Linux.
