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.

Animation

w	Start camera auto-rotation (auto-rotation repeats the last o,s,t-action).
q	Stop camera auto-rotation.
Ctrl-a	Show Animation panel to steer animations
Ctrl-k	(beta) Create animation by storing current geometry as keyframe.

Modeling

a	Add additional vertex to geometry
e	Add element or polygon by picking existing or new vertices
d	Duplicate all visible geometries of a scene by reflection at a point, a line, or a plane. The point, line or plane are determined by marking one, two, or three vertices of the current geometry.
i	Initial pick, e.g. used drag initial points on surfaces.
m	Drag a rectangle to Mark all enclosed vertices.
n	Drag a rectangle to mark all touched elements.
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.
Shift-u	Drag a rectangle to Unmark all enclosed elements.

Rendering

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 usage of depthcueing to fade off 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-j	Toggle usage of lights.
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-s	Toggle anti-aliased rendering.
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 <ctrl> key to select geometry in display.
Ctrl-tab	Select next geometry by cycling through the set of visible geometries of the display.
Shift-o (beta)	Toggle if modeling transformation is used when a geometry is selected by picking and dragging on the geometry, and scene transformation is used when the background is picked with the mouse. Modeling and scene transformation will change frequently depending on whether a geometry or the background is picked. By default, this mode is switched off and switching between modeling and scene transformation must be done using the camera panel.

Deleting

Ctrl-Shift-y	Clear JavaView, remove all geometries and reset display.
Del-left mouse	Keep <backspace> or <del> key pressed and pick a geometry to delete geometry from display.

Panels

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-c	Show info panel of Camera
Ctrl-d or F3	Show console window with Debug information
Ctrl-i	Show Info panel of current geometry if available
Ctrl-l	Show Light panel of current display
Ctrl-m	Show Material panel of current geometry if available
Ctrl-p	Show info panel of current Project if available
Ctrl-t	Show Texture panel of geometry if available
Ctrl-v	Info panel of Viewer respectively display

Apply Methods to Geometry via Method Menu

Menu Shortcuts

Ctrl-n	New geometry dialog.
Ctrl-Shift-n	Load a JVD file with same name as recently loaded model file.
Ctrl-o	Open file import dialog.
Ctrl-Shift-o	Same as Ctrl-o, but additionally load a JVD file with same name if available.
Ctrl-s	Save geometry export dialog.

Emergency Exit of JavaView (application only)

Ctrl-Shift-x

Exit JavaView immediately, no exit box.
