Moving and rotating
Structure files are simply rotated by holding down the left mouse button while moving the mouse. This will rotate the structure in the direction the mouse is moved. The structures can be freely rotated in all directions.
Holding down the Ctrl on Windows or 
on Mac key on the
keyboard while dragging the mouse moves the structure in the
direction the mouse is moved. This is particularly useful if the
view is zoomed to cover only a small region of the protein
structure.
Zoom in (
) and zoom out (
) on the structure
is done by selecting the appropriate zoom tool in the toolbar and
clicking with the mouse on the view area. Alternatively, click and
hold the left mouse button while using either zoom tool and move the
mouse up or down to zoom out or in respectively. The view can be
restored to display the entire structure by clicking the Fit
width (
) button on the toolbar (read more about
zooming).
- Rotate mode
The structure is rotated when the "Pan mode" (
) is selected in the toolbar.
If the "pan mode" is not enabled on the first view of a structure a warning is shown.
- Zoom mode
Use the zoom buttons on the toolbar to enable zoom mode. A single click with the mouse will zoom slightly on the structure. Moreover, it is possible to zoom in and out on the structure by keeping the left mouse button pressed while moving the mouse up and down. - Move mode
It is possible to move the structure from side to side if the Ctrl key on Windows and
key on Mac is pressed while dragging with the mouse.
