* If aSelection is specified, then this selection is used as the target
* of the operation. Otherwise, GetSelectionForCopy is used to retrieve
* the current selection.
*
* This will fire a cut, copy or paste event at the node at the start
* point of the selection. If a cut or copy event is not cancelled, the
* selection is copied to the clipboard and true is returned. Paste events
* have no default behaviour but true will be returned. It is expected
* that the caller will execute any needed default paste behaviour. Also,
* note that this method only copies text to the clipboard, the caller is
* responsible for removing the content during a cut operation if true is
* returned.

* If aActionTaken is non-NULL, it will be set to true if an action was
* taken, whether it be the default action or the default being prevented.
