“xev” lists:

  keycode 50 (keysym 0xffe1, Shift_L)
  …
  keycode 71 (keysym 0xffc2, F5)

if I press <shift>-<F5> regardless if launched from within tmux or
not.

I'm not sure what you mean by “another terminal app”. Another window
in tmux you mean? Starting a 2nd instance of mc in another window
yields the same result.

I just tried it on the console (no X) and the issue vanishes. This
makes my believe it has nothing to do with mc, rather it's a
misconfiguration of my terminal emulator.

Thanks for the nudge in the right direction.
