Toolbar
The toolbar is the global header at the top of the editor window. It groups project-level actions on the left, viewport controls in the center, and history / publishing actions on the right.
Left group — project
| Control | Action |
|---|---|
 | Relu Spatial logo. Clicking this returns to the project dashboard. |
 | Opens the shortcuts modal (shows various keyboard shortcuts). |
 | Opens the in-app issue reporter. |
Center group — scene & preview
| Control | Action |
|---|---|
 | Active manipulation mode (move / rotate / scale). Mirrors the gizmo shown on the selected entity. |
 | Adds a new entity to the scene (cube, sphere, plane, light, camera, etc.). |
 | Launches the preview runtime in a separate window using the current saved snapshot. |
Right group — history & publishing
| Control | Action |
|---|---|
 | Reverts the last scene-affecting action. Bound to Cmd/Ctrl + Z. |
 | Re-applies the last undone action. Bound to Cmd/Ctrl + Shift + Z. |
 | Writes the current scene to disk. Bound to Cmd/Ctrl + S. |
 | Uploads the project to Relu and makes it shareable. |
 | Opens the in-app tour and links to this documentation. |
TIP
Save and Publish are independent. You always need to save before previewing or publishing — preview/publish read the on-disk snapshot, not the in-memory state.
