CTRL+SHIFT stop text printing on the ole Beeb too, but the CTRL to slow 
down the screen idea wasn't there. Prolly because you could read it all 
anyhow. ;-)

I'm sure they did.

Well, <break> slow mine down quite a bit. ;-)

Seriously though, I think holding down any keys will slow down the 
machine to an equal extent. It's just that 99% of the time holding down 
any key other than CTRL or SHIFT will actually do something and hence the 
effect won't be noticed. As far as I know, the actual amount of code done 
for each key is pretty similar.

As I say, I'm not sure about this. My BBC emulator has got a little stuck 
at the keyboard stage and due to other projects, work, beer and women I 
haven't managed to get much further.
