All
Windows – Shows or hides camera objects in all open view
windows.
Current
Window – Shows or hides camera objects only in the current
window (the last window you clicked, marked by a white outline).
Notes
Toggling a camera on displays every component
of the camera: icons, vectors, and a complete frustum, including
the far clipping plane.
The icons are displayed in the active
color only if the component of the camera they represent is active.
For example, the forward vector is displayed in the active color
if either the eye or viewpoint is active.
