How to view an image in its REAL size?

Right now, an image that is say 4000 x 5000 px (larger than my screen) is always shown zoomed out, filling my screen, but like 30% of the real size of the image.

I'd like to press a key and see the image in its real size, cropped.

Edit: Thank you for your reply! Yes, it works, but it opens a new tab, as you said, and then one must click again to zoom. Do you know this Greasemonkey script? https://greasyfork.org/en/scripts/404-mouseover-popup-image-viewer It shows the full-size image without opening a new tab.

Thank you for your nice add-on!

This review is for a previous version of the add-on (3.7). 

The best way currently is to press 'b' or 't' while the pop-up is displayed. That will open the full-size image in a background or foreground tab, where you can pan and zoom the full size image.
