Drag and Drop

By pressing the mouse left button on a single residue or a group of selected residues, the drag and drop mode is activated. The selected residues can be dragged to any part of the drawing canvas. When the mouse button is released the dragged residues will be moved to the final location. If the button is released upon an existing residue, the selection will be added to it, otherwise a new structure will be created containing the selected residues. If the <ctrl> button is pressed the selection will be copied from the original location to its destination, otherwise the selected residues will be deleted from the original location. The selection cannot be dragged outside the current drawing canvas.
