How do I stop Genie from auto-capitalising the surname of a patient that contains Mac or Mc?

Genie likes to be helpful but sometimes its help isn't desired!  In order to stop Genie from changing Old Macdonald to Old MacDonald you will need enter the desired text into the surname text field then hold down the Alt/Option key on your keyboard before clicking out of the text box.  By holding down this Alt/Option key you are telling Genie you don't need its help and will happily keep the formatting you've typed yourself.
