There are only 2 PF keys. "A" is upper left corner next to the power 
switch, and "B" which is just above the key pad.   Just to the left of 
the "B" key is the drv/meter key.   It is probably more convenient to 
set " "B" to read swr and use the drv/meter key  next to it to switch 
meter functions that you will read with the "B" key.

You can always hit the mode key or menu key twice  which will give you 
freq readout and return you to  your original state.

If you are  good at soldering, you can make a box with 4 push buttons 
that goes between mic and rig.   You can use your existing mic, and also 
define the  additional  push buttons that the radio's menus will 
recognize.   I think the box has resistors in it between push buttons 
and  various wires in the mic line.

Colin from this list built one for the TS-2000 a few years ago and 
posted the info here.   The 590 and 2000 use the same 8 pin round mic 
jack, so it should work on the 590 as well.
