How to document string literals?

[Vladimir]

I have a function, which argument can take a certain set of string values.

Here is an example:

const TYPES = {
 "key-one": 1,
 "key.two": 2,
 "keyt<>three": 3
};

function chooseType(t) {
 return TYPES[t];
}

chooseType("key-one");

So, the value of "t" parameter should be only one of keys of TYPES object. 
Those keys are strings and may contain non-alpabet chars.

So I don't understand, how to correctly make JSDoc to describe it.

I know about enumerating all possible values in jsdoc such way:

/** @param {'key-one'|'key.two'|'keyt<>three'} t */

But it looks disgustingly, and I hope there is right way.
