This is similar but not quite the same on all 6 of my (US) keyboards (except it is the same on 2 identical models). SysReq seems to be going away and is only on my 2 20+ year old keyboards. PrintScreen is is even more useless/unsupported for its original operation. But my worst (and most expensive) keyboard axed ScrollLock before PrintScreen. I use ScrollLock a lot under FreeBSD but never noticed it doing anything elsewhere. Bruce
