available help, user help documents which can be displayed while working in a program
Online Help is topic, procedural or reference information delivered through
computer software. It is a form of
User Assistance. Most Help is designed to give assistance in the use of a software application or operating system, but can also be used to present information on a broad range of subjects. When Help is linked to the state of application (what user is doing), it's called
context-sensitive Help.
