Detect browser "back" input for Chrome extension

Question

I want to make a chrome extension which performs a certain action when the user enters the a "back" navigation action.

ie: they click the back button in the browser, or they swipe backwards with 3 fingers on a macbook pro, or if they enter the shortcut alt + left arrow.

How can I detect these actions? Should I create some type of listener or handler which accounts for each one individually?

You can use the webNavigation API.

Start monitoring the details for each transition type that you mentioned. And then try to do something with this information.

chrome.experimental.webNavigation.onCommitted(function(details){
    console.log(details);
});
