adjusing screen resolution in photoshop Options

[turniphead-stuff]

I opened a photo from my computer in my photoshop. I did my editing and what not. Usually, I copy the image and paste it onto a new document because of the huge difference in screen resolution size. A new photoshop document in 72 pixels/inch, while a photo opened in photoshop is 230 pixels/inch.
Well, I forgot to paste it into a new document. Now, as I begin to add text and brushes, I realized that the screen resolution is too high. (Everything is too big). I would copy and paste each individual layer into a new document, but I have about 60 layers.
Is there any way to change the screen resolution on an open document?

^ and if you want to move all those layers to a new document: first, open a new document, then click on the first layer, hold shift, and scroll all the way down and then click the last one you want to copy. then you let go of shift, click on any of the layers [don't let go!] and drag it onto your new document.

but just resizing it is WAY easier, lol.
