Left/Right cursor buttons to scroll the most-central boosts-pane

[revpriest]

Is your feature request related to a problem? Please describe.
I sometimes read at my standing-desk while brushing my teeth which leaves me with only one hand. Mouse-clicking the tiny side-buttons to scroll the boosts-pane sideways can be perilous due to the vibrations from the electronic toothbrush, and anyway, my fingers aren't on the mouse they're on the cursor keys.

Describe the solution you'd like
When I press left or right on the cursor keys I'd like the middlemost boost pane to scroll left or right accordingly.

Describe alternatives you've considered
Currently I have to keep moving to the mouse and clicking the side-buttons. I also try clicking the side-button and then pressing tab, which moves focus into the pane and then does allow left/right to work, but it'd be cooler if I didn't have to touch the mouse.

Additional context
I suppose disabled people who only have one hand might benefit as well as those who are merely diverting their attention while brushing teeth.

@revpriest Phanpy has custom keyboard shortcuts that may help. Pressing j or k will navigate through the post one-by-one. You can try them out and learn more shortcuts via the menu → Keyboard Shortcuts or pressing ?.

Ah. That might do the trick if I exempt the site from Vimium overriding the keypresses. Cheers.
