If you want to see key on the library screen, go to Settings->Library Settings->Song Title Formatting, tap the title or caption field, then add %KEYS% to it (you can tap the Keys button to do this).

Similarly, if you want to change the output of the generated song list when using the "Generate Song List" feature, go to Settings->Library Settings->Generate Song List Format, tap the title field and add %KEYS% to it.
