Type a diagnosis in the Diagnosis entry in the New Data or Edit Macro (or Micro) dialog and then press the Tab or Return key. If the diagnosis is registered, nothing will happen. If not, the Register Diagnosis dialog will pop up. This means that every diagnosis will be compared with all the diagnoses stored in the database whenever you type it. If the Register Diagnosis dialog pops up, confirm the spelling of the diagnosis.
Registering an abbreviation for a long diagnosis (for example, scc for squamous cell carcinoma) as a synonym can reduce the number of key strokes and avoid mistakes in typing.
Some diseases have more than one name. For example, solar keratosis may be called actinic keratosis. If you type more than one name for a disease in the Diagnosis entry in the New Data or Edit Macro (or Micro) dialog, a search by one of the names would bring you only a subset of what you would expected. To avoid this situation, you would better to register all the possible names for a disease as synonyms for the disease. If you type the Tab or Return key whenever you type a diagnosis in the Diagnosis entry in the New Data or Edit Macro (or Micro) dialog, diagnoses registered as synonyms for a disease would be converted to the diagnosis name (not synonym name) of the disease, which makes you keep the one name for one disease policy.
