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
