I like the new scrolling in osx lion. my brother hates it. If you want to turn osx lion scrolling back to normal like snow leopard then:
Turn osx lion scrolling back to normal like snow leopard
- system preferences > trackpad > scroll & zoom
- untick ‘scroll direction: natural’
you are done.
Reversed trackpad, Regular mouse
I use the reversed scrolling setting on my trackpad on my laptop, but I like the normal way on my mouse, to do this, then you can install ‘scroll reverser‘
