     373<LI>The Magnification/Add region menu item requests a location in the
     374  pattern (2Theta/TOF/KeV/d-space/Q) and a multiplier. Data where the
     375  scan variable (2Theta...) is of that value or higher, up to the
     376  next region or end of the pattern are multiplied by that factor. The
     377  factor, must be >0.
     378<LI>Magnification/Edit regions brings up a menu (see below) where the previously
     379 defined regions can be changed. The region boundaries can be moved
     380  and the multiplier values can be changed. If a multiplier is set to
     381  zero (or negative) that region is removed.
     382<LI>Magnification/Clear deletes all previously defined regions
     383<LI>Pressing control plus a positive digit (1,2,3,...9) also adds a
     384  magnification region. The digit determines the magnification
     385  multiplier. Data where the
     386  scan variable (2Theta...) from the mouse position up to the
     387  next region or end of the pattern are multiplied by that factor.
