calc: Displaying Selections

 
 11.1.3 Displaying Selections
 ----------------------------
 
 The ‘j d’ (‘calc-show-selections’) command controls how selected
 sub-formulas are displayed.  One of the alternatives is illustrated in
 the above examples; if we press ‘j d’ we switch to the other style in
 which the selected portion itself is obscured by ‘#’ signs:
 
                 3    ...                  #    ___
          (a + b)  . . .            ## # ##  + V c
      1*  ...............       1*  ---------------
              . . . .                   2 x + 1
    If the customizable variable ‘calc-highlight-selections-with-faces’
 is non-‘nil’, then the non-selected portion of the formula will be
 de-emphasized by using a less noticeable face (‘calc-nonselected-face’)
 instead of dots and the selected sub-formula will be highlighted by
 using a more noticeable face (‘calc-selected-face’) instead of ‘#’
 signs.  (Customizing Calc.)
