Selection Sets
Editing actions can be carried out on a subset of the molecule.
First invoke the adjust tool with Tools:Adjust or on the toolbar with 
. Then select a portion of the molecule as described below. Finally carry out the desired action with the selected set of atoms.
Creating a Selection Set
Several methods exist to select atoms/bonds:
- Click each atom
- Drag a box around a group of atoms and bonds
- Click one one atom and then choose Adjust:Select Molecule to select all connected atoms and bonds
- Double-click in the background to select everything
Removing atoms/bonds from the selection set:
- Click on a selected atom or bond to remove it from the selection set
- Single-click in the background to de-select everything

Working with Selections
Rotate Selection about horizontal or vertical (X or Y) axis: Choose Adjust:Rotate Selection; drag to rotate the selection along an in-plane axis; press esc to exit selection mode
Rotate Selection about perpendicular (Z) axis: Choose Adjust:Rotate Selection; alt-drag to rotate the selection along the out-of-plane axis; press esc to exit selection mode
Translate Selection horizontally or vertically (X or Y): Choose Adjust:Translate Selection; drag to move the selection in-plane; press esc to exit selection mode
Translate Selection perpendicularly (Z): Choose Adjust:Translate Selection; alt-drag to move the selection perpendicular to the plane; press esc to exit selection mode
Cleanup Selection: Choose Cleanup:Selection Only followed by the desired cleanup action. Atoms that were not selected will not be affected.
Delete Selection: Choose Adjust:Delete Selection which deletes the selected atoms and their bonds from the molecule
Duplicating a Selection
Copy: Make a selection set and select Edit:Copy or Edit:Cut
Paste: Select Edit:Paste
Move: The newly duplicated atoms and bonds are selected and Translate Selection mode is automatically activated; translate the new atoms to the desired location. They may be oriented with Adjust:Rotate Selection.
