How do I scale just the time portion of the animation view timeline?

I’m trying to condense the animation into something more manageable for a 30s animation but I can’t seem to zoom out for just the timeline. I need 30s or more visible in the timeline but I don’t want my curves to be essentially flat because it’s zoomed out so far. How do I do this?

Use shift + zoom to zoom vertically, and Control + zoom to zoom horizontally
