Is there a scroll bar or other setting allowing the user to adjust the frame or time resolution. Say you have an animation that is 400 frames and and you want the dope sheet to show frames 100 to 110, for example. Can you do this without grouping all the keys and using the scale command?
There is a Preview Range to preview part of an animation.
Press P in the animation editors to draw preview range, or you can press S and E in the timeline, with preview range enabled.
If youre after another way to scale keyframes in the dopesheet, I dont think there is one.
Note the scale origin is the time cursor.
The render frame rate can also be adjusted.
