More mystery keys

Few of you are rushing to the defence of the Pause/Break and Scroll lock keys. The most commonly stated reason for keeping either would seem to be that they would leave a hole in the keyboard if we didn't have them.
Steven Oakley has a suggestion for Pause/Break. 'It can be very useful in halting the booting of a PC, to read those troublesome error messages that are sometimes key to a diagnosis,' he says.
Jonathan Allport, at CML Group, is horrified: 'Scroll Lock is used in the Unix world, where it will prevent unwanted screen updates while you're trying to look at something important.' We've missed the big story, he says. 'The real question is: what does SysRq do?'
We demand that the powers that be tell us.
