'  1) a parameters frame for viewing and altering the parameters '
'     or method of the currently selected spectrum.'
'  2) a main display area for viewing spectra graphically.'
'  3) zoom controls for getting a closer look at spectral features.'

'will zoom in to that region.  If you click with the left button at a point '
'in the main axes, the main axes display will zoom in to that point for a '
'more detailed look at the data there.  Similarly, you can click with the '
'right mouse button (shift click on the Mac) at a point in the main axes to '
'zoom out from that point for a wider view of the data.  In each case, the '
