Reddit Gallery Keys — uherman

Reddit Gallery Keys lets you flip through Reddit image galleries using the
left and right arrow keys, instead of clicking the on-screen chevrons.

How it works
When you open an image post on reddit.com and the gallery lightbox appears,
pressing ← or → steps between the images — exactly like clicking the < / >
buttons. That's it. No popup, no settings, no buttons added to the page.

Works in any language
The extension finds Reddit's navigation buttons by their structural HTML
attributes rather than their visible text, so it works regardless of the
language your Reddit UI is set to.

Privacy
Reddit Gallery Keys runs entirely inside your browser. It does not collect,
store, or transmit any data, and it does not communicate with any server.
It only activates on reddit.com.
