Title:  	Prevent the backspace key from causing the browser to go back in history

The recent extraction of text manipulation functions slightly changed the backspace key behaviour. The new interface was only returning true if an operation was generated as a result of the call (aligning with all other public functions on the class). This means however that back-spacing when there is no available positions (e.g., at the beginning of a document) was causing the browser to navigate back a page.
