The Zoom in and Zoom out buttons can be used to control the zoom factor of the canvas. Alternatively, the mouse wheel can also be used. Simply scroll with it when the canvas is in focus.
The Zoom all button optimizes the size of the structure to the canvas size. The Zoom to selection button displays only the selected structure on the canvas.
The vertical and horizontal scroll bars appear when the structure is bigger than the canvas or when some structural parts are out of the canvas.
The following selection modes are available in Marvin JS:
To select an atom, bond or group, click or select it (while the active tool is either the Rectangle selection or the Freehand selection). To select a structure, double-click an atom or a bond of it while the active tool is either the Rectangle selection or the Freehand selection. To unselect, click an empty place on the canvas.
To move a single atom or bond, drag it on the canvas while one of the selection tools is active.
To move a selected molecule, move the it by dragging one of its atoms. In the case of graphical objects, drag the selected graphical object by its line.
To delete an atom or a bond, click the Delete tool on the tools toolbar, then click the atom or the bond. Alternatively, you can select the parts you would like to erase by holding the left mouse button and dragging. You can delete a previously selected area by clicking on the Delete tool or pressing the Delete key.
