# Study Workspace Overview
> The unified workspace where you build, edit, view, and compare your ranges.
## The Study workspace
The Study workspace is the heart of RangeSharp. It's where you build your ranges, edit individual hands, view your strategies, and compare ranges side by side — all in one place.
Unlike tools that separate editing and viewing into different apps, RangeSharp combines everything into a single workspace so you never have to switch contexts.
## Layout
The Study workspace has three main areas:
| Area | Position | Purpose |
| ----------------- | ----------- | ------------------------------------------------------------------------------- |
| **Strategy tree** | Left panel | Browse and navigate your strategies and spots using the decision tree |
| **Range grid** | Center | The 13×13 hand matrix where you view and paint ranges |
| **Detail panel** | Right panel | Action palette, frequency controls, notes, combo statistics, and training stats |
### Above the grid
* **Spot context bar** — Shows the current spot's position, action line, and stack depth
* **Toolbar** — Access overlays, compare mode, import/export, screenshot, and training shortcuts
## Working with the strategy tree
The left panel displays your strategies as a tree. Each strategy expands to reveal its spots, organized by position and action line.
* **Click a spot** to load it into the grid
* **Right-click** for context menu options (add spot, duplicate, delete, rename)
* **Drag and drop** to reorder spots within a strategy
* **Mastery badges** appear next to each spot, showing your training progress
## Working with the range grid
The center of the workspace shows the 13×13 hand matrix. This is a canvas-based grid for smooth, responsive interaction.
* **Click** a cell to toggle the active action on/off
* **Click and drag** across cells to paint multiple hands at once
* **Shift+click** a cell to open the frequency adjuster (Pro/Elite)
* **Arrow keys** to navigate between cells
The grid updates and saves automatically — you don't need to click a save button.
