If you have a three-button mouse, you can use its third button or wheel to
zoom and pan:
1 Roll the wheel to zoom in or out.
2 Press the wheel, and drag to pan.
NOTE You can use any third-button pointing device to pan the image. To
enable this, choose the Pan/Zoom option on the
Viewports panel on page
7545 of the Preferences dialog
Interface
Both the viewport and floating versions of the ActiveShade window have the
same controls as a
rendered frame window on page 5885 . In an ActiveShade
viewport, the toolbar is off by default. In a floating ActiveShade window, the
toolbar is always visible.
TIP In an active ActiveShade viewport, you can toggle toolbar display by pressing
the Spacebar. (This is a main user interface shortcut, so the Keyboard Shortcut
Override Toggle can be either on or off.)
