Scroll lock has fallen into such extremely infrequent use that some of the lighter-weight Linux desktop environments, such as Xfce, don't support it at all. Therefore scroll lock can be regarded as a defunct feature in almost all modern programs and operating systems some keyboards lack scroll lock altogether. In modern GUI environments, scrolling is usually accomplished using means such as scrollbars or scroll wheels.
