Google Chrome shortcuts

Hi guys. I have been looking for a web browser for my laptop for when it is running off of battery since I have made it so that the processor's second core is disabled when on battery... so it is technically a single core 800mhz processor.

Opera web browser takes up a lot of processing power, and Firefox isn't what it used to be, so I have been trying Chrome and so far it runs great on a single core 800mhz processor once I installed the Flashblock extension.

However, I miss the superior easy shortcuts of Opera... For example:

-alt+enter automatically logs you in to your account no matter what website as long as the account is saved (best feature)

-Hold right clicker on mouse and click left clicker to go back, vice versa to go forward.

-F2 when in fullscreen mode gives you the url so you can easily go to whatever website.

And some more similar to those that I can't think of right now.

Is there an extension that changes the shortcuts to make them similar to Opera, or is there a way to do it manually? If that isn't possible, is there an extension that adds mouse gestures similar to those of Apple laptops? (two finger slide to go back, etc.)

The reason why I ask you guys of this is because I have searched the extension page and there are several extensions and I am not sure which ones are best.
