Steps to reproduce the problem:
1. Go to http://www.dailymail.co.uk/news/article-5607759/Police-identify-missing-dog-testing-sings-favourite-tune.html (or perhaps any Daily Mail link)
2. If using Mac OS X, Google Chrome, press Command-Left or Alt-Left on Windows
3. Daily Mail loads in a different story but most web pages let you use Command-Left to return to the previous page you were on.

What is the expected behavior?
I would like Command-Left to do the same thing as pressing the left-arrow (back) in the address bar in all cases. This works for most web pages and when it doesn't work, I have to  I do not want a web page to be able to use that keyboard shortcut to reassign the behavior in order to get more advertising revenue.

What went wrong?
I think this is just some providers capturing a keystroke using javascript and I'd like to turn that behavior off or make sure that no one can take over that behavior because I have to use the mouse / trackpad in those cases.

Did this work before? N/A
