Keysight E4982A Troubleshooting Manual page 15

The online help has context sensitive help, which is a great
feature of the E4982A help. It allows you to get information
about the selected softkey by pressing the Help key in the
E4982A or by pressing F1 in a keyboard attached to the
E4982A or by clicking the help button in a dialog box. With
context sensitive help, users can receive information quickly
about the area the user is working in the firmware of the
E4982A. It provides information relevant to the task that
needs to be accomplished and reduces the time to search
relevant information required to complete a task.
