Chrome extension for scrolling your webpage without moving your palm. By default the browser only allows you to scroll the page by the arrow key, or page up/down key. Those keys are usually located at the edge of the keyboard. As a result you will have to move your hand around when you scroll.
This extension allows you to scroll with the H, J, K, L key, just as in vim, or the A, W, S, D key just like you do in a PC game.
You can install the extension from chrome web store.
Left hand: S, right hand: J
