What about using a constant HashMap?

I tried to use it, but it doesn't compile as all methods for creating a HashMap are not const and other options like a sorted Map of characters would add too many lines.

Use a shorter name here so that the default function fits into one line.

I think the formatting doesn't care about the length of the default function when there are too many arguments. I tried to shorten all names and it still moves them on a new line.

Use tuple assignments here like:
const (EXECUTE, REMOVE_LINE, NON_PRINTABLE): (u8, u8, u8) = (ctrl_key(b'E'), ctrl_key(b'R'), ctrl_key(b'P'));

I added non printable characters rendering using the new key bind CTRL+P, that also lets you hide them. Now whitespaces (
·), tabs (├──┤), linefeeds (␊) and other control characters will be rendered (I encountered a problem here, some terminals are not in fact able to render UTF-8 characters, so I tested the code of the character that appears on render and all codes are correct). The problem now is that nightly formatting is messing around with all if statements and other declarations that I tried to write on a single line, so the number of lines is above limit by almost 50 lines. I tried modifying the fmt config file, adding other rules that would help reduce the number of lines, but I couldn't force it to format everything more compressed. Even though I can compress them by hand, the code won't pass the tests. Any tips for refactoring the code would be awesome.Issue: #2
