This has been driving me mad for ages - I cant believe I cant figure this out.
When Im editing keyframes in the Curve Editor, Nuke will often auto-reframe the window to show the enitre frame range. I could be zoomed right in to select and modify a keyframe. I select it and go to drag it and boom - suddenly it has zoomed back out again to a wide view (and the subtle adjustments I was trying to do to the keyframe are blown away). I cant figure out what triggers it - it seems to be if I select keyframes, or try to drag keyframes - the window view will just snap to a wide framing showing the full length of the timeline.
I want to diable this "feature" but as I dont even know what it's called I dont even know what to search for! There are no obvious preferences for "snapping" that I can find.
