• Rst - restores the last structure saved by the editor.
• Edt - activates/deactivates the Edit mode.
• Tx- - moves (translates) the structure to the left.
• Tx+ - moves the structure to the right.
• Ty- - moves the structure towards the observer.
• Ty+ - moves the structure away from the observer.
• Tz- - moves structure down.
• Tz+ - moves structure up.
• Rot - rotates the structure to follow the dragged cursor.
• Tra - moves the structure to follow the dragged cursor.
• Rx- - rotates the structure clockwise about the x axis.
• Rx+ - rotates the structure anticlockwise about the x axis.
• Ry- - rotates the structure anticlockwise about the y axis.
• Ry+ - rotates the structure clockwise about the y axis.
• Rz- - rotates the structure clockwise about the z axis.
• Rz+ - rotates the structure anticlockwise about the z axis.
• H2O - unchanged - toggles the visibility of water molecules.
In the above it should be noted that the sub-edit modes that the translation
and rotation buttons initiate act on the molecular structure and not just its
image. Real change results from these operations, unlike what happens in
View mode.
Note that the Ty+ and Ty- buttons, do not `zoom' out and in as happens in
the View mode. In Edit mode the structure is displaced only about 0.1 A in
either direction and is used to help with optimisation, as will be shown later.
Note also that it is permissible to click the axis rotation buttons (Rx+, Ry- etc)
after the Rot button to obtain a mouse controlled rotation about the indicated
axis. Normally the axis rotation buttons rotate the structure by a prescribed,
fixed amount.
Finally and importantly note there is no UNDO button!
