Press H to enable or disable picture-in-picture on Hulu
Press H while watching a video on hulu.com to extract the video into "picture-in-picture" mode. This creates a floating window with just the video inside of it, which you can resize as you wish and move anywhere you want on your screen. In this mode you can switch to a different browser tab and not have to stay focused on the Hulu one, just don't close it or the video will stop playing.
To put the video back inside of its tab, either click on the video where it says "Back to tab", or go to the Hulu tab and press H again.
"H" is for "hover", if you have trouble remembering the shortcut.
