Essential Graph Toolkit is an add-on that expands Blender's Graph Editor with precise keyframe manipulation operations. It provides dedicated tools to push and pull keys relative to a pivot, mirror selected keys across adjacent values, snap keyframes to neighboring values, and apply rapid ten-percent value scaling.

The toolset includes curve isolation capabilities that allow users to show or hide translation, rotation, and scale curves independently across multiple objects. It also introduces a custom keymap system restricted to the Graph Editor, enabling personalized shortcuts for playback and keyframe navigation without causing conflicts with 3D Viewport hotkeys.
