Ugh, just ran into this "improvement" today. The old keyboard shortcut for the SET PAGE BOXES dialogue to trim or crop multiple pages was Control+Shift+T (the original post incorrectly identifies the command). Now it's been reassigned to "insert blank page"? Why couldn't Adobe come up with a new shortcut for that if it thought people wanted a shortcut for that?

We're talking about the dialogue box here, not the cropping tool. See attached image, which came from https://helpx.adobe.com/acrobat/using/crop-pdf-pages.html

Also, the "single key accelerators" setting users don't always want to enable. So the current suggestion to enable that setting and then hitting the "C" key is inadequate. Furthermore, the crop tool is NOT the same as the dialogue box for multi-page trimming.

This is just another poorly thought through change to the program. Users get accustomed to using software a certain way and become efficient at it in their workflow. Changing it without good reason (like really, really good) is a problem. Compounding that problem is not letting users reassign the shortcut back to what it used to be.

This has been an issue for years: https://community.adobe.com/t5/acrobat-discussions/set-page-boxes/td-p/12168710

I use it multiple times daily! I hate the new Acrobat and have gone back to using the previous version! How deep can you hide the crop tool. I have tried to add it to my toolbar, either can't find it or it doesn't stay available. This is for me one of the most frustrating updates ever.

Hi Julie, it took me a while (I'm using Pro 2017, after using X for a long time) but I found out that it's now Shift+Command+P (in Mac; assuming it's now Ctrl Alt P in Windows) instead of T.

Let me know if it works!
