Copy structures

In Marvin JS, there are many ways to multiply your structures.

Inside the application

Context menu

First of all, you can select the structure, then choose Duplicate from the context menu. This command works only inside the application and can duplicate any object which is displayed on the canvas.

Multiply the molecule with Ctrl+Drag :

You can move a copy of the selected structure by pressing the Ctrl button and dragging the selected structure. When you do this, a "+" sign appears beside the cursor. A copy of the selected structure is placed on the canvas when you release the left button, and the original object remains selected, so it can be multiplied several times.

Copy-Paste buttons

When you click the Copy button, a copy of the selected structure will be created on the clipboard, and the Paste button places the copied structure onto the canvas.

Please, note that in some browsers, copying and pasting the content from/to Marvin JS is possible only via the keyboard shortcuts. In these browsers, after clicking the Cut, Copy or Paste toolbar buttons, a message appears on the canvas:
