Code Scroll shows the whole file in your theme’s colors next to the code, with errors, changes and bookmarks marked on it. Drag the frame to scroll, or rest the pointer on the map to see the code under it.
The map also labels TODO, region and MARK comments and class names, highlights
every occurrence of the selected text, and gives rendered Markdown previews a map of
their own. It works in IntelliJ IDEA, WebStorm, Rider, Android Studio and other
JetBrains IDEs from version 2026.2.
Code Scroll is free and open source under the MIT license. It collects no data and never goes online. Install it from Settings | Plugins | Marketplace in your IDE or from JetBrains Marketplace. The source and build instructions are on GitHub.
Bug reports go to GitHub issues or rustam@n69.in, which is to say, straight to the entire staff.
