import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.ST;
import org.eclipse.swt.custom.StyledText;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class StyledTextClearKeyBinding {
  public static void main(String[] args) {
    final Display display = new Display();
    final Shell shell = new Shell(display);

    StyledText styledText = new StyledText(shell, SWT.V_SCROLL | SWT.BORDER);
    styledText.setText("12345");

    styledText.setKeyBinding('i' | SWT.ALT, ST.TOGGLE_OVERWRITE);
   
    //clear
    styledText.setKeyBinding('i' | SWT.ALT, SWT.NULL);
    
    
    styledText.setBounds(10, 10, 100, 100);
    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch()) {
        display.sleep();
      }
    }
    display.dispose();
