Add/Remove Explicit Hydrogens

Switches explicit H atoms to implicit ones and vica versa. Explicit hydrogens are displayed with atoms joining its neighbor while implicit hydrogens are displayed by atom symbols only.

Add/Remove Map Atoms

Adding atom maps is an automatic assignment of map numbers to all selected atoms of a reaction by using the automapper tool.

Add/Remove Data

Attach/Remove data like stoichiometry coefficient to the molecule.

Add/Remove Absolute Stereo (CHIRAL)

Sets/Removes chiral flag for the molecule.

Add Multi-Center

Add a multi-center attachment point representing a group of atoms.

Add Position Variation Bond

Create a variable point of attachment to represent a connection point to a group of atoms.

Add No Structure

Places a No Structure label on the canvas.

Link Node

Specifies query structures containing rings or chains of variable size.

R-Logic

Allows setting additional R-group conditions such as occurrence, rest H and if-then expressions to R-groups in the R-logic dialog.

Transformation > Drag Selection

The selected part of the molecule can be moved by dragging the mark box with your mouse or with the proper arrow keys.

Transformation > Rotate in 2D

The selection can be rotated in the plane of the canvas with changing coordinates.

Transformation > Rotate in 3D

The selected part of the molecule will be rotated according to the chosen rotation mode.

Transformation > Switch Transformation (space)

You can switch between dragging or 3D rotating the selected molecular parts by hitting the space bar.

Transformation > Flip

Flips the structure on the canvas. The submenu allows you to choose horizontally or vertically.

Transformation > Mirror

Flips the object horizontally, inverting tetrahedral stereochemistry. The submenu allows you to choose horizontally or vertically.

Transformation > Invert

Reflects the selected fragment(s) through the geometric or arbitrary center.

Format

Change atom and bond drawing properties.

Add To My Templates

Adds the selected structure to the My Templates group located in the Template Library and on the Advanced Templates Toolbar.

Atom Label Editor

Allows changing the atom label on the canvas. Atom labe properties can be on the appearing toolbar.
