Midnight Commander Key Bindings

To change the default key bindings for Midnight commander on Arch Linux. From the man pages :

  Redefine hotkey bindings

Hotkey bindings may be read from external file (keymap-file).  Initially, Mignight    Commander creates key bindings using keymap defined in the source code. Then,  two  files  /usr/share/mc/mc.keymap  and  /etc/mc/mc.keymap are loaded always, sequentially reassigned key bindings defined earlier.  User-defined keymap-file is searched on the following algorithm (to the first one found):

              1) command line option -K <keymap> or --keymap=<keymap>
              2) Environment variable MC_KEYMAP
              3) Parameter keymap in section [Midnight-Commander] of config file.
              4) File ~/.config/mc/mc.keymap

Thus we can just

$ cp /etc/mc/mc.default.keymap ~/.config/mc/mc.keymap 

Then edit the keymap file as required. Its useful to save the file within a repository such as git when complete.
