Using the menu keys
The actions of the unshifted and shifted variable menu keys for both solvers are
identical. Notice that the Multiple Equation Solver uses two forms of menu
labels: black and white. The L key displays additional menu labels, if
required. In addition, each solver has special menu keys, which are described
in the following table. You can tell which solver is started by looking at the
special menu labels.
