Rotate geometry by moving mouse inside viewer window and drag while left mouse button is pressed. Usually, rotation is the default mode in the viewer.

Press right mouse button to select major interaction mode from popup menu, or use keyboard keys to temporarily switch between different modes (just keep a button pressed to switch mode temporarily):

Transformation

o	Rotate surface (initial mode for perspective camera) similar to a space ball. Orbit mode.
s	Scale surface, drag in vertical direction
t	Translate surface in xy-plane (initial mode for orthogonal cameras)
z	Translate surface in z-direction
c	Center camera on object (object is centered and not scaled).
f	Focus camera on object (object is centered and scaled).
x	Drag a rectangle to be eXpanded to fill display. Or pick a new center without expanding.
r	Reset camera and viewer, geometry returns to default position
Left Mouse	Depending on the mode, drag, pick and select the geometry in the viewer
Right Mouse	Show popup menu to select major modes and others actions.

Auto-Rotation

q	Stop animation in viewer.
w	Start animation of last action in viewer (rotate, translate, scale).

Modeling

a	Add additional vertex to geometry
i	Initial pick, e.g. used drag initial points on surfaces.
m	Drag a rectangle to Mark all enclosed vertices.
p	Pick a vertex and drag it. To see picked vertex enable display of vertices in menu Inspector->Object->Material of control panel, picked vertices are magenta).
u	Drag a rectangle to Unmark all enclosed vertices.

Selecting

Shift-a	Toggle display of edge aura around edge.
Shift-b	Toggle display of bounding box around current geometry.
Shift-c	Toggle display of center of geometry (pending).
Shift-d	Toggle display of depthcue fading of far away items.
Shift-f	Toggle display of small coordinate frame.
Shift-g	Toggle display of xy-grid.
Shift-h	Toggle display of information at mouse tip.
Shift-i	Toggle display of background image.
Shift-l	Toggle display of border around display.
Shift-m	Toggle magnet mode of vertices, i.e. highlight if nearby vertices.
Shift-p	Toggle usage of painters algorithm.
Shift-r	Toggle display of copyright information.
Shift-t	Toggle tag mode to move all marked vertices.
Shift-x	Toggle display of coordinate axes.
Shift-y	Toggle fast z-buffer mode.
Shift-z	Toggle z-buffer mode.

Selecting

Ctrl-left mouse

Pick geometry with left mouse while holding control key to select geometry in display.

Deleting

Del-left mouse

Pick geometry with left mouse while holding control key to delete geometry from display.

Ctrl-s or F1	Show control window to modify e.g. material and display settings
F2	Close control window
Ctrl-a or F4	Show Animation panel to steer animations
Ctrl-i	Show Info panel of current geometry
Ctrl-m	Show Material panel of current geometry
Ctrl-d or F3	Show console window with Debug information

Apply Methods to Geometry via Method Menu

Menu Shortcuts

Ctrl-o

Open file import dialog (application only).

Emergency Exit of JavaView (application only)

Ctrl-Shift-x

Exit JavaView immediately, no exit box.

To modify appearance of the geometry press F1 or Ctrl-s to show the control window and select the material panel. Be sure to have the mouse focus inside the viewer, otherwise Windows help might appear. To hide the control window press F2.

Go to applet Viewer Demo to test/exercise the navigation of the camera.
