Not in Premiere. You might find a third-party utility that would do this, or perhaps in your mouse drivers, but it would likely be a system-wide change, then.
Make a feature request for this, if you please: Adobe - Feature Request/Bug Report Form
Place your cursor over the Source or Program Monitor and the Scroll Wheel will hopefully do what you want of it.
Oh, heh Read that wrong I thought you meant that you felt that up = left and down = right was backwards. Mea culpa... but Craig set you on the right track.
Side bar: this has been a popular question as of late. I guess I don't see the advantage of this, but to each their own. I routinely work with 8-10 layers of video and am rarely scrolling up and down, but then again I usually make my tracks pretty small. I'd still suggest making a feature request, but if up/down scrolling breaks left/right scrolling, I'd be an unhappy camper
I also am happy with the way left / right and up /down scrolling works in the timeline...so dont break it.
Wow. It just seems like a huge oversight on Adobe's part. Every other NLE I've used down the track listing in the timeline instead of across. This is also true for every single window in Windows or OS X, every browser, etc. It seems really moronic to have a timeline scroll left and right instead of up and down when you scroll the mouse's wheel.
Sorry... just venting a bit because it just slows me down.
Go to the bar on the right side of the Time line and scroll up and down to your hearts content.
I guess in other editors you used Linear means Vertical.
In Premiere Linear is horizontal ...ie. aligned with the footage one is editing and the way time works.
Seems logical to me because I edit along the footage from head to tail.
I guess its what you get used to.
I have to agree with the previous post. Every NLE I've ever used scrolls left/right. (Media Composer, Media 100, Premiere, Premiere Pro, Pinnacle) That, to me, is the more intuitive use of the scroll wheel.
In After Effects, which is more of a 'vertical' editor, the default is to scroll vertically. It makes sense, but I do often find myself trying to move along the timeline by rolling the wheel.
