## Selection and the gizmo

![Screenshot: multiple selected objects](https://www.softellion.com/img/docs/spectrum/multi-select.png)

- A single click selects the topmost object under the cursor; <kbd>

Ctrl

</kbd>

 + <kbd>

click

</kbd>

 builds a multi-selection.
- The transform gizmo appears when **exactly one** object is selected. Multi-selections get selection boxes only.
- Switch the gizmo mode with <kbd>

T

</kbd>

 (translate), <kbd>

R

</kbd>

 (rotate) or <kbd>

S

</kbd>

 (scale), or hide the gizmo entirely with <kbd>

Q

</kbd>

 (selection only); the toolbar in the top-left corner of the viewport does the same.
- Drag the gizmo arrows to move, rings to rotate, boxes to scale along the corresponding axis.
