While most common operations can be performed using only a mouse, a few operations require a
combination of both keyboard and mouse. Note that these operations only work in View Mode.
Note that in these descriptions, the screen is assumed to show the X-axis (horizontal) and the Y-axid (vertical),
with the Z-axis coming "out" of this plane. The possible combinations and their results are outlined below.
Selecting a blank portion of the screen:
Mouse only - Dragging the mouse results in rotating the molecule around the
X- and Y-axes.
<Shift> + Mouse - Rotation will occur around the Z-axis.
<Ctrl> + Mouse - The molecule will be translated along the X- and Y-axes.
Selecting a single atom:
Mouse only - The label for this atom is shown. (If the charges button is pressed,
the calculated charge on this atom is also shown).
<Shift> + Mouse - The selected atom is highlighted. If this atom is already highlighted,
this operation will cause the highlight to be removed.
A
button is provided that will allow automatic re-scaling and re-centering of the molecule. This button will also
remove all highlights from the displayed structure.
