How to zoom out in the Animation Preview window?

I’ve got a character with some animations that I want to preview, but when I drag it to the animation preview window, it’s so large that I can’t see it. I tried to zoom out with middle mouse scrolling, ALT-Clicking, but it doesn’t work. Any ideas? Thank you.

You currently can’t zoom the Animator view in/out, but apparently they’re aware and it’ll be added in a future version.

5 years pass and we cant make zoom in preview window.
