Drawing help and shortcuts
Click two points or drag to add bonds. Atom tools replace an existing atom or add one in empty space. Carbon hydrogens are implicit; use H to draw one explicitly when helpful for stereochemistry. Use the circled + or − tools to add or remove charges. Click or drag with Eraser to erase. Escape cancels a bond. Ctrl/⌘ Z undoes; Ctrl/⌘ Shift Z redoes. With Move, drag an atom or Shift-drag a whole connected structure. Use Double to draw the new carbon–carbon double bond.
