Two fingers scrolling

Two fingers scrolling is like; moving a window on a list or moving a list under a window.
I would prefer to move the window on the list than to move the list as it is now on Mint....
But maybe it is a way to set it, if so excuse-me...
However, it feel strange to, for example, while using vlc, to scroll from right to left to push up the volume while the bar control is moving the other way and to move up to down to go further in a movie.
Anyway I like a lot this two control maneer on vlc...
And I also like mint as I'm a very new user instead of Ubuntu; it seem to be less crash...
I hope I was clear enough about this X and Y axis choice. It would have been more easy in French for me....
