The following explanation by from Egmont Koblinger  seems relevant:
This seems to be a problem with the console-data or kbd or whichever
similar package of Linux distros... They offer multiple keymaps, and define
function keys differently in them.
E.g. type "loadkeys us" -> with the U.S. keymap pressing Shift+F4 will do
what you'd expect from Shift-F6.
But type "loadkeys ru" -> with the Russian keymap Shift+F6 works as
Seems that the kernel's builtin keymap makes the Shift key offset the
function keys by 10 (drivers/tty/vt/defkeymap.map says «keycode 64 = F6
F16» and later «string F16 = "\033[29~"»), and this is what mc expects too
(mc.lib: «f16=\\e[29~»). Unfortunately, many keymaps, including the
probably most widely used "us" wants to be able to assign separate action
to F11 and Shift+F1, so they shift by 12 and define «keycode 64 = F6 F18».
There's nothing mc could do about this right now, first all the keymaps
should be made consistent.
