When a user tabs to a field which has field help, the field help text appears at the bottom of the screen near the status bar. While field help is useful to everyone, it is particularly important to someone using a screen reader. A sighted user can read the field label to understand the field's general purpose and look at the field help for additional information. However, the field label is not always accessible to someone who is blind. When someone who is blind tabs to an input field, the screen reader will read the contents of the field help, the type of control and then the value of the input field if it is not blank.
Screen readers rely on the field help to tell users about the edit field.
Most screen readers provide a special hotkey which allows Notes users to query the field help line if they need the help repeated. Open the Field Properties box and select the Advanced tab. Write a brief description in the Help Description field. If a form contains similar fields, ensure that the field help is unique for each field. Radio button controls require meaningful field help.
