[MU/D].................. If a multiplication/division instruction is stored in memory, cancels the data. The
[D%] ...................... If a multiplication/division instruction is memorized, cancels the data.
[+/-]....................... Inverts sign of the displayed number at key entry.
[IC+]......................
[IC±]
[S] ......................... If an operation is performed by the [=] or [%] key in auto accumulation calculation
[C/E] ..................... If pressed at key entry, operates same as the [CE] key.

The result of pressing the [CE] key after the [#/P] key depends on the state before
the keys were pressed.

The result of pressing the [C/CE] key after the [+/-] or the [#/P] key depends on the
state before the keys were pressed.
