bug#25204: 25.1.50; I can't change the scroll-lock setting when Emacs has the focus

I agree, because otherwise a bug report like this would have been filed earlier.

In fact, I also don't use that key for anything.  I found this bug
while investigating another problem: In my office PC, the scroll-lock
state sometimes, somehow, ends up being "ON" (without pressing the
scroll-lock key).  That annoys me while working in MS-Excel, and I
suspect that Emacs has something to do with that phenomenon.  But I
still haven't found a recipe to report that problem.

Yes.

FWIW: IMO, the default behavior should be let the scroll-lock key
toggle the scroll-lock status.  Definitely.

Thanks.
