Dialog Bar - Right
This is actually a special type of Control Bar, which resides on the right side of the Main window. It can be turned on or off with the Dialog Bar - Right command in the Display menu.
Cursor Mode. In Atom ID (identification) mode, clicking on the left (or only) mouse button will identify atoms and give bond lengths and angles - see Atoms at Cursor.
The cursor in this mode is a cross. Clicking and dragging with the right mouse button (Windows) or control+button Macintosh) will switch temporarily (as long as the button is down) to the the Rotate mode, below.
In Rotate mode, clicking and dragging rotates the structure. In most of the window, rotation will be around the y and z Cartesian axes, in the plane of the screen. Clicking and dragging near the left or upper edges will rotate about the z axis, perpendicular to the screen. The cursor is a quadruple arrow when rotating on x and y, and a circular arrow when rotating on z.
The Clino (clinographic) View checkbox will switch viewing with the Clinographic rotations.
The Set Center button defines a new center point - use this to "focus" or "zero in" on a specific area or point in the plot. After clicking on this button, an dialog informs you that the next mouse click in the graphics window will define a new center point. After clicking on a point, the drawing will then be displaced so that that point will be at the center of the viewing area. It may be more useful to think of the result as the viewing area being centered on the point selected. Displacements set in this way may be changed in the Centering/Displacement dialog in the Input2 Menu.
With the Rescale buttons, you can "zoom" in or out. The actual factor applied is 1/(1+x) for down scaling, and (1+x) for up scaling, where x is the amount in the edit box converted from percent to a fraction. In the Maximize size for each view and Universal maximum modes this changes the Rescale factor, which may be reset manually in the Scaling dialog in the Input2 menu. When in the Fixed scaling mode, the actual scale factors for screen, print and pen plot are changed. This behavior is a change from pre-V5.0 ATOMS, in which rescaling always changed to the Fixed mode.
Orientation buttons. These buttons will actually remove accumulated rotations and return to either the original orientation or the initial orientation. They perform the same functions as the Remove Rotations option in the Rotation menu.
The original orientation means the orientation before any rotations, including the alignment of a slice, and the rotations of the Initial Orientation dialog in the Input2 menu, have been made. This gives the standard orientation of the crystal (the first one in the case of multiple crystals) with respect to the reference Cartesian coordinate system. The initial orientation is that attained after the rotations just listed have been made, if any of them were actually used. See also Coordinate Systems.
Delete Tool. This allows "deleting" (see Deleting Atoms and Atom Labels) groups of atoms by creating a polygon with the mouse. All atoms within the projection of the polygon can be marked for non-plotting.
The Show All button allows immediate restoration of all atoms marked as non-plotting. See the Atom/Bond Plot States dialog (Input2 menu) for more options regarding non-plotting atoms.
Move Labels. Individual atom, bond and angle labels on generated atoms can be moved from their centered position. This button turns on and off a special cursor mode (for the left button only) in which clicking and dragging labels will move them. This should not be done until the very latest stages of preparing a drawing, since rotations are liable to make the changed locations invalid. All label displacements can be removed for each type of label in the dialogs in the Display menu.
The Inter. bonds (inter-molecule bonds) combo box (only displayed if there are bonds between molecules or fragments) gives several options for display of inter-molecule or interfragment bonds. If Highlighted is selected, such bonds are shown in normal colors while all other atoms, bonds, etc. are dimmed. Other possible highlighting of molecules or fragments is ignored.
The Reset Scale button calls the Reset Scaling and Centering dialog. This allows reversion to the last setttings, before interactive changes with the Set Center or Rescale buttons (above), or in the Fullscreen 3D mode.
The Stereo Angle edit box sets the angle between left- and right-eye views in the 2D Stereopair, 3D Stereopair and Quad Stereo Drawing modes. This angle should be negative for cross-eyed viewing of stereopairs
The Perspective Distance edit box sets the perspective distance (not relevant in most cases if perspective viewing is turned off in the Perspective dialog). This can affect the perception of depth in stereoscopic modes.
