This is the patient select screen.  As shown below, if there is a current customer, the screen will show all the patients for that customer.  If there is no current customer, no patients will be displayed, and the 'All Patients' box will be ticked.

If the required patient is displayed, just click it to select it.

To search by patient name, enter the full or partial name (see using wildcards) and click the Find button, or press the Enter key or Alt-F.

To search the patients belonging to all customers (and not just the current one), click the 'All Patients' checkbox.

To include deactivated patients, set the 'Active' pulldown to 'Both'.

To search by Identity rather than name, click the 'Search Identities' checkbox.
