So my very talented 1 year old turned the sreen upside down on my laptop, but won't tell me how to put it back again. Any ideas?

[Sputnik]

He did it randomly pressing the keyboard. I have tried:
pressing every key
restarting
reading the manual relating to soft keys (combined function keys)
phoning DH, who is geeky, even he doesn't know.

I am running XP on a Toshiba Equium.
Help!

Try Alt and the up arrow at the same time.

Yes!
Alt Gr up arrow did the trick, thank you so much

My kids have done the same, as you might have guessed.

And yours is the second identical query on mumsnet I have answered!!!

Glad it worked. I think you can disable it, but don't ask me how.
