The Dynamic Display module contains two toolbars. The first toolbar shown below is called the Standard Toolbar, since its layout is similar to that of other Windows® applications.
The second one is called the View Toolbar, since it is used to rotate, pan and zoom in and out on structure animations.
The two toolbars are described in the following two sub-sections. Please note that all toolbar buttons have tool tips that provide brief summaries of their functions.
As an alternative to using the View Toolbar, you can use the arrow keys (ßàáâ), in combination with the Shift and Ctrl keys, to pan, rotate and zoom. The final Shortcut Keys section below gives the details.
The Standard Toolbar provides quick access to the most frequently used commands. All of the commands are available in the menus and as such have been described already. The table below lists the menu commands that correspond to the buttons on the Standard Toolbar.

The View Toolbar has buttons for rotating, panning and zooming. This section describes these operations and then summarises the function of each of the toolbar buttons.
There is a pair of rotation buttons for each of the X, Y and Z axes. These rotations are all Screen Relative.
To rotate the structure clockwise about a particular axis, you click on the left-hand button of the pair for that axis. Similarly, to rotate the structure anti-clockwise about that axis, you click on the right-hand button of the pair. The amount by which the structure is rotated for each click is indicated (in degrees) in the menu on the toolbar. You can change this by selecting one of the values from the list or typing in a different value. The angle is saved on exiting the program and restored when the program starts again.
Four toolbar buttons are provided to pan the display. In each case, the structure moves in the direction that the arrow points.
The two zoom buttons are used to zoom in towards and out from the centre of the current view. The operation of this facility is largely self-explanatory. You use the button on the left to zoom in closer to the structure, and the other button to zoom out.
