Octohint is a Chrome add-on developed by Rongjian Zhang that brings IntelliSense hint functionality to GitHub. With Octohint installed, users can enhance their code viewing experience on GitHub by accessing a range of helpful features.

When using Octohint, simply hover your mouse over a token to view information about it. This allows you to quickly understand the purpose and usage of the code you are inspecting. Additionally, by left-clicking on a token, you can see all the references to that token, providing valuable insights into how it is utilized throughout the codebase.

For Windows and Linux users, Octohint also offers the ability to go to the definition of a token by holding down the [Ctrl] key and clicking on it. This feature makes it easy to navigate through complex codebases and understand how different components interact with each other.

It's important to note that Octohint is a client-side tool, meaning all code analysis is performed within your browser. This ensures that your code and actions remain private and are not sent to any external servers. Octohint is available as a free add-on for Chrome, making it a convenient and accessible tool for GitHub users.
