After login, the main window of the GUI client (UnitedChart browser) is displayed:

Going from top to bottom, the main window contains the following:

• Title bar - The title bar displays the name of the program followed by the name of the currently logged in user.
• Pull down menus - The pull down menus are used to access the less frequently used areas of the software.
• Tool bar - The tool bar contains the frequently used software options. To select a tool bar button either click on it with the mouse or press the underlined letter while holding down the ALT key. The tool bar also contains an information text box which displays appointment statistics.
• Enter button - The enter button appears to the left of the keywords input field. The text within the go button changes to indicate the action that will take place when then ENTER key is pressed (or the enter button is clicked).
• Keywords input field - The keywords input field, which is used to enter search text, appears to the left of the enter button.
• Appointment date - The appointment date identifies the date of the appointments in the following list.
• Message count - The number of new messages, in your inbox, is displayed between the appointment date and clock. Viewing your messages clears the message counter.
• Clock - The clock shows the current time. This may be the time on the PC or the network server, depending on system configuration.
• Appointment list - The appointment list shows the appointments for the current day. If the logged in user has schedules, the list contains just that user's appointments. If the logged in user does not have schedules, the list contains the appointments for all the users, at that location, that do have schedules. That is, doctors see only their appointments while assistants see all their doctor's appointments.

The keywords field can be used to search for appointments, patients, internet web sites, phone numbers, and more. Certain capital letters expand as described below. Turn off CAPS LOCK to prevent unintentional expansion of entered text.

• Appointment list search - As characters are typed into the keywords field, the appointment list is searched to see if a name matches the entered text. If so, the name in the appointment list is highlighted and the enter button is changed to display Chart if the logged in user has schedules or Appt if not. This is done so that the default action for doctors is to view a patient's chart, while the default action for others is to modify the patient's appointment.
• Patient search - If the text entered into the keywords field does not find an appointment in the list, then the highlight bar is removed from the appointment list and the text is used to search for patients. The enter button is changed to Find to indicate that pressing ENTER will perform a patient search. To force a patient search add a trailing space to the keyword text.
• Internet web site - If the keywords begins with http then pressing ENTER goes to that web site, using the default browser. Type a capital W to expand to http://www..
• Internet white pages search - If the keywords begins with phone# then pressing ENTER performs an internet white pages search on the number that follows. Remember to include to area code. Type a capital P to expand to phone#.
