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".


I'd like to conclude with a positive statement, but I can't
remember any. Would two negative ones do?       -- Woody Allen
