Use the s,d,f,j,k,l, and space keys on your keyboard to type as you would on a perkins brailler. Files can be saved with a ".txt" extension.
The JavaFX perkins brailler text area logic is entirely self-contained, so the component can easily be reused by adding the following to your application's FXML file:
<?import JBrailler.PerkinsBraillerTextArea?>
<PerkinsBraillerTextArea fx:id="brailleTextInput"></PerkinsBraillerTextArea>
