for ages I've been used to using the alt+left arrow key shortcut to go page a page on my pc but since i got my new laptop the only alt key which will actually make this command work is the left one, every time I try to use the right one (my preferred) it just rotates the whole screen exactly as if i had pressed ctrl at the same time even though i haven't even gone near it :/
how do I fix this!!!!!!!
i'm using windows 8.1
