You mean in BASIC? In assembly, it's BIOS call #0180 and #0183.

Those keys are located in the actual keyboard matrix, but in a new row, for
which there was no space reserved in the system RAM area. In assembly, you
can read them using BIOS call #0141.
By the way, the key names are not "Yes" and "No", but (if I remember
correctly) "Execute" and "Cancel".
The application switch can be read using I/O ports.

This was published somewhere (probably either MCCM or Sunrise Magazine) a
long time ago. You can modify the BIOS that is used in R800 DRAM mode,
disabling the PAUSE key. Once the BIOS no longer reacts to it, you can react
to it in your program (probably by reading some I/O port).

Interesting. Could you give a list?
I know only "PLAY #1", which is used for MIDI.
You can find a lot of interesting articles on the turbo R (published before
in MCCM) on The MSX Plaza by Alex Wulms:

Note: the turbo R articles are Dutch only (for now?).
