Zoom in and out in Animation editor

Correct me if I am wrong but you can not zoom in and out in the animation editor(at least on a mac). Such a small thing would be a big deal for people coming from ableton or after effects coz it will allow to create longer animation(of minutes) and precisely place each keyframe on the timeline. You will be able to use touch for creating composition directly on a timeline rather than having multiple instances of animation COMPs which control the same thing at different times.

Zoom is middle-mouse-button dragging in the Animation Editor, the same as it is in the Network Editor and CHOP/TOP/3D viewers. Note that a 3-button mouse (or 2-button with push-down scrollwheel to act as middle mouse button) is a requirement for using TouchDesigner.

The network editor does also move with the scrollwheel, but this is a different interaction with different behavior than middle-mouse-drag zoom. Using the scroll wheel will navigate you through the project heirarchy (ie. go up a network when you zoom out, or go inside a network when you zoom into a component), using middle-mouse-zoom is pure zoom of the network to any zoom amount, it will not navigate you to a different network at any time.

Hope that helps.
