# Subject navigation mode

The subject navigation control replaces the subject search mode on the Time and Events Schedule, CRFs, and forms under source verification, and allows you to navigate through the Time and Events Schedule and forms based on an ordered list of subjects within a site.

The subject navigation control:

- Displays a drop-down list of all subjects in the current subject's site, with the current subject selected.
- Displays the Subject Number and Initials.
- Orders subjects according to the Subject Order feature, if applicable. For more information, see Subject order.

You can:

- Click the right or left arrows to navigate to the Time and Events Schedule or CRF for the next or previous subject.
- Click the icon to return to the search mode.

When navigating by subjects, the current form always remains on display. When the form is not available for a particular subject, the form area on the screen displays a statement saying the form is not available.

If the current form is a repeating form, navigating through subjects shows you the summary views.

If the current visit is a dynamic visit, you can only navigate through subjects that have that particular dynamic visit. Subjects without that dynamic visit are skipped.

Note: Because the Data Viewer has its own navigation controls, the subject navigation control is not needed and is hidden when you are using the Data Viewer.
