Delete Molecules

   Edit > Delete Molecule(s). If there is more than one molecule on the screen, click All, then OK in the Molecule Expression dialog.

Menubar:	Edit > Delete Molecule(s)
Command Line:	ZAP area_expr

ZAP deletes molecules and their associated data structures from program memory. It clears the molecule area. All associated display structures (e.g., dots, ribbons, ...) are removed from the graphics screen as well.

Delete Backgrounds

   View > Manage Backgrounds > Delete

The system removes any displayed backgrounds.

Clear the Screen of All Molecules and Backgrounds

   Edit > Clear All

Delete Annotations

   View > Annotate

The system opens the Annotation Palette.

   On the Annotation Palette, click Select All.

   On the Annotation Palette, click Delete (press Close).

The system removes any displayed annotations and closes the Annotation Palette.

Reset Scaling, Translation, and Rotation

   Click the icon and click Everything (press Q).

The system returns to the original scale, translation, and rotation settings.

Undo Last Operation

Each work area has a one level stack associated with it. Prior to any operation performed on a molecule, the current state is saved on this stack. If an error occurs in the performance of the operation specified by the command, the system uses this stacked copy to return the molecule data to a valid state. Similarly, if you choose to reverse the action of a command, this stacked data is available to return to the previous state.

• Restore Contents of Molecule Area to Previous State
• Force Saving of Molecule Area(s) Contents to the Save/Restore Stack

Notes:

1. The "current state" saved to the stack includes the coordinates, atom types, bond types, etc.

2. UNDO does not reverse the effect of labels or colors.

3. If you want to reverse the effect of the LABEL command, use UNLABEL.

4. You can not reverse the effect of the COLOR command (in the Graphics manual). If you have a color scheme you wish to save, you need to save the molecule with that color scheme.

Restore Contents of Molecule Area to Previous State

Menubar:	Edit > Undo
Command Line:	RECOVER mol_area
	UNDO Restores contents of all molecule areas (RESTORE M*).

If the AUTOSAVE is OFF, RECOVER copies molecule structures on the stack to and restores them to the molecule area, the stacked copy is retained. However, the UNDO command does not do anything. If the AUTOSAVE mode is ON, the copy is restored and the stack is popped. (See SET AUTOSAVE in the Graphics Manual).

LIST MOLECULE * BRIEF is used, identifies molecules that currently have recovery stack contents by an asterisks "*" in the left column.

MONITOR pairs are not saved and, therefore, are lost if RECOVER is executed. This is because MONITOR pairs may involve more than one molecule area.

Force Saving of Molecule Area(s) Contents to the Save/Restore Stack

SAVE mol_area

Only useful when AUTOSAVE mode is disabled. If AUTOSAVE mode is in effect, any changes to molecule data structures cause an automatic save of the molecule data structure before any operation is done.

After a SAVE operation is performed, any RECOVER command causes contents of this stack to be restored to the molecule area. Similarly, if a catastrophic error occurs in the program's operation, a recovery initiated from within the program causes this saved molecule to be restored.

See SET AUTOSAVE for information on automatic saving of molecules on the recovery stack and for an explanation of the operation (in the Graphics Manual).
