On a standard keyboard, the F and J keys are provided with ridges, they are the only keys that have these ridges. The principal function of the ridges is to help the users to correctly identify the two keys and to rightly position their hands on the keyboard without having to look down on it. This is especially true for users who have vision defects and also in situations when there is no light to check out the keys during usage.
