10.1.3 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.
