Originally I said helpful, but I've changed my mind! When I do that it does turn the caps lock off - but it turns it completely off! Now I can't turn it on at all. So I have to keep my finger on shift to depress it for every letter I'm typing as they need to be all caps. I'd like the caps lock key to work without the attempt to "helpfully" remind me that it's on with the indicator that shows up exactly where I'm typing! I don't need to be reminded that I've got caps lock on - I'm looking at what I'm typing!
I understand that perhaps a vision impaired person might want a reminder but then this particular visual reminder is not helpful to them either.
