Sometimes you may find it not convenient to have a too long auto-repeat delay and rate. However, you can easily adjust them, both in console and X.
kbdrate -d 150 -r 40
xset r rate 150 40
Both of the commands above will set the auto-repeat delay to 150ms and auto- repeat rate to 40chars/sec, in console and X, respectively, though. This will make a faster scroll in pagers like less, while not having a bad impact on character input. At least for me.
