It can't be detected. You posted how mc has dedicated definitions for each
terminal. In your case was:


I suppouse mc look what terminal is running (using $TERM) and do dedicated
things for it. Since mc don't have support for st (yet ;)), the only
solution you have is doing local modifications to your config.h and get a st
similar to your xterm. Like I said, this kind of things are not portable,
and some sequences will work for you, but will not work for others. I
usually avoid this kind of binding due to this problem.

It is similar to the case of arrow keys in emacs, Shift-left doesn't work in
emacs under st with TERM=st, but it works in st with TERM=xterm (and I am
pretty sure is not a problem of the definition of terminfo).
