I do not know how MC works, but I know it is highly configurable using
a lot of text files. You should be able to assign to F3 what you wish.
You find this configuration file in /usr/vnc/etc/mc.
For the general question of monitor a binary, there is in Linux
a very nice command called "strace", which saved me more times.
If you type:
# strace /bin/ifconfig 2>log
you can track all system-call, opened files, etc used by the command,
in this example "ifconfig".
Do not tell me how it works: I consider this command a true miracle.
No strace in muLinux, but I will put a copy in the MISC section.
Probabily, it do not work with NCURSES app as MC, but you can try with
# strace mc 2>log
and to ispect the file "log".
