Keyboard shortcut for cropping pages - changed?

I upgraded to Acrobat DC.

I'm trying to crop by the traditional command of shift+command(control)+T

It brings up the insert pages box. I want the crop box.

I put my mouse over the crop button icon and it says it's shift+command+T

Why won't it come up?

The Adobe support didn't seem to know what I was talking about.

Apparently the program is wrong? Is there anyway to make it what it was?

thanks,

Bryce
