Clean: cleans the structural formula using an external service.skeleton mode: displays all C and H atoms instead of skeletal display.Color mode: display atoms and bonds using colors.Lasso select: select atoms and bonds by drawing a freehand selection area.Rectangle select: select atoms and bonds using a rectangular selection area.Drag: move the entire molecule (you can already use the left mouse button for this).Each tool has different behavior for the right mouse button: You can delete the selection using the DEL key or using the eraser tool. If you have selected a separate fragment, you can rotate it by dragging an atom in the selection. You can add/remove atoms and bonds to the selection by clicking them. Selection tools: all these tool can be used to drag the current selection or individual atoms and bonds.Undo/redo: undo or redo your recent changes.Eraser: erase atoms, bonds or the current selection.NIST Chemistry WebBook (~30.000 spectra).
