{CHANGELOG}.md

{README}.md

This Tampermokey script allows you to navigate through Stand Still, Stay Silent webcomic by using Left/Rgiht Arrow Keys.

To apply this scriptlet, you need to install Tampermonkey plugin for your browser first; then simply go to its dashboard, switch to "Utility" tab, fill in the following address to the URL box

https://gist.githubusercontent.com/CXuesong/27ff62fef5456dfbebd00a02b5546fa5/raw/SSSS%20Helper.js

and click "Import" button. You may try it out; happy reading!

p.s.

I've only tested the script on Chrome. If you come across bugs on other browsers, please leave me a comment. Thank you!
