You may get better quiescent consumption by using CMOS
gates to supply power to the PIC. Each button sends a high
to a 4081 gate. The resulting high from the gate goes to the
PortB pin and also is diode-ORed with other gates to drive
a bypass transistor that supplies the PICs Vcc

   that could be an interesting solution. The tactile keys I'll use are
double poles. I could put the pole A of each key in parallel with each other
and use the keys as ON momentary switchers.

   The most strange thing would be how to make the key "latch ON" the power
and the PIC "latch OFF".

   Well, something to think...

   Best regards,
