Allow non WikiWord for the new topic name
It's usually best to choose a WikiWord for the new topic name, otherwise automatic linking may not work. Characters not allowed in topic names, such as spaces will automatically be removed.

Overwrite the copy destination if exists
By default, copy does not happen if the destination topic already exists. If this is checked, the destination topic is deleted if exists before copying takes place
