The replacement list for text replacement can also be modified by the user, allowing the user to use shortcuts. If, for example, the user is writing an essay on the industrial revolution, a replacement key can be set up to replace the 'word' "ir" with "industrial revolution", saving the user time whenever he wants to type it.
