Let's say I'm currently on page X, and the previous page I came from was page Y. Is there a keyboard shortcut to open page Y in a new tab right next to the tab with page X?

Currently my only solution is to hold down cmd (for mac) and click the back arrow button, but again, I'm looking for a keyboard shortcut. I know CTRL + T opens up the same page in a tab right next to the current one, but I have to wait for it to load then press backspace to go back one page.
