What carries over

• Element letters. Point at an atom and press C, N, O, S, P, F, I, H, B or K to change it. Press Enter over an atom to type any label, such as Cl, Br, OMe or Boc.
• Bond keys over a bond. Point at a bond and press 1, 2 or 3 for single, double or triple, W, H, B, D or Y for wedge, hash, bold, dashed or wavy, and F to swap its ends.
• Rings over a bond. Point at a bond and press 4 to 8 to fuse a ring of that size, or A for benzene.
• Editing. Ctrl+Z, Ctrl+C, Ctrl+V, Ctrl+A and Delete do what you expect.

ChemDraw classic

Open Settings › Shortcuts and switch Shortcut set to ChemDraw classic. It adds ChemDraw's atom-label keys: point at an atom and press e for Et, Shift+P for Ph or y for Boc, among others. Where a ChemDraw key was taken by an Athanor command, ChemDraw's meaning wins, and the message says which commands gave up their key.
