This extension allows you to assign keys to click elements on a web page for you.
The configuration is currently stored in JSON per site, with the JavaScript "event.key" (see
https://keycode.info to find values for keys) as the JSON property key and the CSS selector for the element as the JSON property value.
Example config for
https://apod.nasa.gov:
{
"ArrowLeft": "hr + a",
"ArrowRight": "center a[href^=\"ap\"]:last-of-type"
}
