But even keys like ~ and ` have a use in things like csh. I use them on most days.
Even keys like & and % and \. I have few keys I have no use for.
But really, WTF is the "§" for? I have never, ever, ever, used § apart from this blog post!
And ± is the other part of that key, but even that I struggle to use. I was rather puzzled but the use of ± in the Netherlands on things like train times. They would have ± and a time. But they used it in a context of "approximately", like "~", so a train may be ±5 minutes late, which makes no sense. If really ±5min it would be either early 5 minutes or late 5 minutes, or maybe between 5 minutes early and 5 minutes late. They would use ±5 as meaning +5±1 or ~5min late, i.e. late, by 5 minutes or around that. Very wrong use of ±.
But I never use ± or § so WTF is it wasting a key on my keyboard?
P.S. http://en.wikipedia.org/wiki/Section_sign says it is a UK specific keyboard symbol, why?!
