Is there an UNDO command in Pro DC? Another question; can I shrink a document physically? I need the 100% contents in 90% of the same page or 80% of the same page

Hello, I need help in these two issues for Acrobat Pro DC;

1) Is there an UNDO command when I make an error command; eg; I deleted a wrong content.

2) Can I shrink a document physically (not kb) giving me space all around the page; In other words, I want the 100% contents moved into 90% or 50% of the document keeping the center intact. Preferably, I would like to increase the margins (top/bottom/left/right) as I choose.

Thank you

Oh my thank you for putting this resolve up, all the responses seemed to miss the point of the persons issue and making it ssomewhat complicated. I had wanted to undo some highlighting, 

to summise anyone who has googled and are reading this thread ...

There an undo button in Adobe DC but you have to go find it and add to your tool bar

right click over the tool bar and select Show Edit Tool

There is a circular undo sign - tick it.

hurrahhhh!

To undo some editing you've done use CTRL + z key at the same time.
