How to disable multiple selection ?

When CTRL is hold , clicking on text in the editor will add a new cursor.
While this might be useful, I would like to disable it (I already use CTRL to display custom links)

Is there a simple way to disable multiple selection ?

The configureMouse option can be used for this.

Thanks a lot. This fixed it :

var cm = CodeMirror(editorDiv, 
	configureMouse: (cm, repeat, ev) => 
		return { addNew : false };
