wikipedia fast category browsing hotkeys

Adds keyboard shortcuts to browse wikipedia pages in the last visited category page. Visit category page, then press a/d.

1) Visit wikipedia. 2) Go to the bottom and click a categories page. Alternatively, press shift+d or ctrl+shift+right to go to a random categories page of the current page. 2.5) probably click the first article on the category page 3) right/d goes to next article. left/a goes to previous article. up/w goes back to category page. r/down goes to a random page. Basically, now you can mash right to read lots of wikipedia pages. 💖 ~~~ Have fun ~~~ 💖 PS: If you want to edit keys or write custom functions, I recommend to download the javascript and write it as a userscript for an extension like Tampermonkey. That's faster to update than a browser extension. PPS: Here's a sample URL of an advanced search that returns only category pages. Replace in the URL "psychology+books" with %s, and add the link to your browser's search engines with a convenient keyword like "wicat" or "wikicat": https://en.wikipedia.org/w/index.php?search=psychology+books&title=Special:Search&profile=advanced&fulltext=1&ns14=1 (darn... now that I'm using the search feature, I want search pagination hotkeys too. I left a userscript for that here: https://github.com/noido/userscript-wikipedia_hotkeys/blob/master/wikipedia%20search%20backforward.js )
