This is only an approximation depending on one's vi-ness.  If you use vi
mode and the hjkl exclusively you can do this, but when you start hitting
the arrow keys you get 4 key interrupts.  You can do something like 
while :; do
cat /proc/interrupts
sleep 1
done

in one window and press various keys in another one.  You'll see that not
every key increments the number by two.
