Natural sort order in Midnight Commander

To my knowledge there are not any plugins or extensions to MC, I looked through the features list and did not see anything either (https://github.com/MidnightCommander/mc). Though it has been discussed here:

Yes, of course you can put your preferred shortcuts in ~/.config/mc/mc.keymap to override the default in /etc. don't forget to put the section. e.g [main] , [panel].

if you want to change the default keymap, but you don't know what to type, you can always refer the format in /etc/mc/mc.default.keymap

this is mine

[panel]
Sort = alt-!
SortPrev =
SortNext =
SortReverse = alt-@
SortByName = alt-#
SortByExt = alt+$
SortBySize = alt-%
SortByMTime =  alt-^

according to Use a hotkey to toggle between two preferred sort orders and sort hotkey
