Computer Screen?

[CH1957]

Can anyone please tell me how to get my computer screen back the right way up??!! My lovely grandson has just pressed a button and the screen is now sideways on. Ive tried pressing everything and its not going back. Very strange typing sideways LOL

On iPad so can't see a normal keyboard but it's one of the keys near the space bar on the right hand side and the arrow keys x

Sorted it thanks. Its the alt + ctrl + up arrow - on Windows 7.
