[ADVANCED\]UV_PREVIEW /BROWSE [Ataper] [/FILE FileIn] [Drop]]

Use a "split window" previewer instead of just one window. The bottom window displays full spectra for all tapers, the top window is a user-controlled zoom of one of the tapers, with spectral line identifications if a catalog is available. The cursor is called and the user can adjust the zoom display with it. Press H for help, E for exit.

Ataper indicates the taper number (default: last one).
