For polygonal, circular, annular and pie ROI's there is a special dialog to select and edit all the
parameters. The ROI definition parameters can be saved into a .CTL file and reloaded using the
File menu like any control file. Note that the selected ROI can be advanced in any activated
spectra display by pressing the "+" and "-" key from the numeric keypad.
