Old Fogies
The old fogies among us will recall that you can get any character using the Alt key and number pad - this is very awkward on some laptops but OK on keyboards with actual number pads.
£ = [Alt]156
@ = [Alt]64
I have used this often enough over the decades that I remember 156, and of course @ is the last character before A which is 65.
On my present laptop with number pad and Windows 7 it is essential to ensure that Num Lock is on. I am not sure that is always the case.
Now just remind me one more time - what day is it?
