Key dip is the distance the key on a piano travels between its rest position and the position when the key is pressed. This is usually 10mm or 3/8 of an inch. It is adjusted by adding or removing paper punchings to the front rail of the key. A shallower key dip can lead to a lighter touch and easier repitition, whilst a heavier kep dip can give a greater variety in expression though feels heavier. Even key dip throughout a piano is essential for good action regulation and even touch.
