I generated a private key using this website: https://www.stellar.org/account-viewer/#!/
I was supposed to write down the private key but I didn't and I lost it. I have since unplugged the internet from my Mac and kept Google Chrome open (but the tab is closed) and have not used the Mac any further.
Is it possible the private key I generated on that website could still exist in my computer's RAM??
EDIT: I found it!!! To anyone who comes to this post and finds this, I closed the tab and dumped 4-5 hours later and I still found it. The computer was kept on and Google Chrome was not closed. Do not give up hope!
