Abstract:

Many technical writers are developing usability skills and leveraging them to help improve the product interface. Help is being delivered within the interface itself. Drop-down lists of topics related to an interface component, hint text below a GUI field, and other such embedded user assistance models allow users to get help without leaving the application interface.
