When typing, my right fingers always resting covering 4 arrow keys (provided it's a full-sized keyboard and arrow keys are separated from the rest with enough blank space). I use right fingers to reach Home/End/PgUp/PgDn buttons, INSERT/DEL on numeric. So it's quite useful to have them all close-by.
