This \*(CT is only active when the `t' toggle is \*O and the `1', `2',
`3' and `!' toggles are \*F, thus showing individual \*(PU results.
It assumes a platform has multiple cores of two distinct types,
either multi-threaded (P-Core) or single-threaded (E-Core).
While normally each \*(Pu is displayed as `%Cpu0, %Cpu1, ...', this
toggle can be used to identify and/or filter those \*(Pus by their
core type, either P-Core (performance) or E-Core (efficient).
The 1st time `5' is struck, each \*(PU is displayed as `%Cp\fBP\fR'
or `%Cp\fBE\fR' representing the two core types.
The 2nd time, only P-Cores (%Cp\fBP\fR) will be shown.
The 3rd time, only E-Cores (%Cp\fBE\fR) are displayed.
When this \*(CT is struck for the 4th time, the \*(PU display
returns to the normal `%Cpu' convention.
If separate\fI performance\fR and\fI efficient\fR categories are
not present, this \*(CT will have no effect.
