The “Soup.io vi keys” user script enables jumping from post to post on soup.io using the vi keys (j for next, k for previous; n and p are supported as well). As it is a user script, you will either need Firefox and the Greasemonkey extension or Google Chrome Version 4 and up in order to use it.

The source code can be found at Github.

“Soup.io vi keys” is hosted at userscripts.org where you'll also find a convenient install button.

You can also find a directly installable copy of the source code here.

The script allows you to use the following shortcuts on soup.io:

• J or N: Jump to the next item
• K or P: Jump to the previous item

The scripts is enabled on all pages matching the pattern http://*.soup.io/*. If you want to also enable it on soups that are addressed by custom subdomains, you need to add these soups manually. To do this in Firefox, go to “Tools > Greasemonkey > Manage User Scripts”. In the dialog, select the “Soup.io vi keys” script on the left side and add the desired page to the list of included pages using the “Add” button.
