Use the H, J, K, L keys to Scroll Your Page
You can now use the H, J, K, and L keys to scroll your page without moving your hand.
This is useful if you are trying to go through a website or browse a site, and you don't want to move your hand. It's also useful if you have a small phone with a small keyboard, or if you are using the on-screen keyboard on your phone.
You can also use the A, W, S, and D keys to scroll your page. You don't have to use the arrow keys or page up/down keys anymore.
This extension can be useful to web developers and to anyone who uses the browser or the browser on their phone.
