Ok, Reason, does not have a mouse scroll zoom, like where you push a mod key then scroll to zoom in and out, although it does have time ruler scrolling (Shift) and a vertical resizing (CTRL), the worst prog for zooming imo....
With ableton, the scrub zoom is everything, although there are still scroll bars, vertical in usual place, and horizontal at the TIME bar at the bottom, not to be confused with the measure bar at the top. Then above that you have the overview scrub zoom (making words up here), click and hold this and the world is your oyster, this feature is also in your clip view.
Another good feature is in arrangement view, select a part of any track, whether it has any data in it or not, then simply double click the measure bar at top and it will zoom into that portion! Also works in clip view.
Never used the + n - keys tbh, they are well too far away from my left hand.
Someone hinted about having that keyboard shortcuts wallpaper as your desktop, i leaned the lot in 3-4 wekks, and its sped thing s up a-LOT! holla if you need link...
Big up ableton.
