# Finding an object bubble
To interact with an object, you need to identify the location of its object bubble. For many objects, the object bubble is placed at the object's center. Object bubbles are normally invisible, but you can temporarily make them appear for all objects that you can modify. This includes shared objects and objects that you have added.
* To make all object bubbles appear, hold down the controller trigger or left mouse button. A faint outline appears at the location of the object bubbles. Alternatively, see [#toggling-object-bubble-visibility](#toggling-object-bubble-visibility "mention").
Object bubble outlines
Note that the object bubble isn't always at the centre of the object.
If you target the object bubble for an IFX and then press either the left mouse button or the controller trigger, the name of the IFX is displayed. You can then access the control menu. For more information, see [Accessing the control menu](/engage/advanced-features/modifying-objects/accessing-the-control-menu.md). To target an object button on a VR device, point your controller at it. To target an object bubble on a desktop device, adjust your view so that the object bubble is at the center of the application window.
## Toggling object bubble visibility
You can make the object bubbles remain visible, without the need to hold down a mouse button or controller trigger. And then return them to hidden.
* To toggle object bubble visibility on desktop devices, press the **B** key on the keyboard.
To toggle object bubble visibility on any device, complete the following steps:
1. Open your menu or tablet, and then select **IFX** .
2. On the **IFX** page, select **IFX settings**  in the upper-right corner of the page.
3. On the **IFX Settings** page, turn on the **IFX Selection spheres** are visible toggle.
