What it does#
NotebookLM Mindmap Controls is a Chrome extension that augments Google's NotebookLM mindmap view with the controls it should have shipped with: keyboard navigation, predictable zoom, and smooth panning.
NotebookLM auto-generates a mindmap from your sources, but the default UI is mouse-drag only — clumsy on a trackpad, unusable from the keyboard, and the zoom step is too coarse for dense graphs. This extension layers on:
- Keyboard shortcuts for zoom in/out, fit-to-screen, recenter
- Smoother zoom with finer increments
- Pan with arrow keys instead of drag-only
- Recenter on selected node
The result: you can actually explore a NotebookLM-generated mindmap as a knowledge graph, not as a static diagram you have to wrestle with.
How to use#
- Install from the Chrome Web Store (button below).
- Open any NotebookLM notebook and switch to the Mindmap view.
