Where can I find keyboard key names using in mc.keymap?

Question

I want to assign some actions to key bindnigs in Midnight Commander like Alt+[ or Alt+].
Where can I find "code names" for this (and other) keys?
For example I already found some keys:
` = "prime"
{ = "lbrace"
} = "rbrace"
< = "lt"
> = "gt"

Thanks.

grep'ing the Midnight Commander source code, the file you want to look over is 'lib/tty/keys.c', with the relevant section commented "Alternative label"

Here is the relevant section, followed by a link to the file at the project's official repo.
