For all those keyboard users like me. 1H has a builtin keyboard control to navigate across the site as well as other things you can do without touching the mouse. You can bring up the shortcuts popup by pressing SHIFT + / or ? on keyboard. Some of those key bindings are similar to most of the other websites like reddit RES or Gmail.
Take a look > Click > Category Menu > Click > Keyboard shortcuts.
