There are really two interpretations of this question, with different answer.
Example ^C.
I As everybody knows Wordstar (and IBM before them) has defined this key
as an editor command, scroll half a page down.
You want KEY to return 3. This is accomplished with fiddling with the

You have made a game. You want to make it impossible to interrupt the game,
preventing the gamer to falsify the high scores.
This is accomplished by manipulating traps. You can instruct linux
to ignore the trap associated with ^C.
That is a "system call" buried in layers of c-code landing at
NR_signal or some such.
