Recovers the state of the frame before the last operation that you did.
Redos the last undo.
Cleans the document (in the standalone up, there is a New item in the File menu).
Removes the selected part from the model.
Selects and marks all atoms in the molecule, so that it can be rotated, moved, deleted, etc. This is the only chance to recover parts of the molecule that are outside the display area - select all, go into move mode and move the molecule using a visible part of it.

This will transform hydrogens, which are directly connected to another atom, separate atoms connected by a single bond.
This will delete bonds to hydrogens and add hydrogens directly to their parent atoms.
Sets the order of all bonds so that every atom is saturated.
Sets the order of all bonds to single.
This changes coordinates of atoms a length of bonds to standard representation.
Changes properties for this frame. Current properties are: author (who generated this model), generation date and software. Additionally, a cas number and checksum can be given.
