This generates a mapping from a key cap (one or more characters) to a PUA code, for use with `&displayMap`. Three output formats are supported: - .txt: tab-separated string format, with three columns: PUA, Key Cap, and plain string. The PUA and Key Cap columns are formatted as Unicode Scalar Values, e.g. U+0061, and the plain string is the original key cap string. - .md: formatted for documentation purposes. Generates a Markdown table (GFM) with PUA, Key Cap, and plain string. The PUA and Key Cap columns are formatted as Unicode Scalar Values, e.g. U+0061, and the plain string is the original key cap string. - .json: returns the final aggregated data as an array of strings, which can be joined to form a JSON blob of an object with a single member, `map`, which is an array of objects. **Signature:** ```typescript getStrings(format?: '.txt' | '.md' | '.json'): string[]; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | format | '.txt' \| '.md' \| '.json' | _(Optional)_ file format to return - can be '.txt', '.md', or '.json' | **Returns:** string\[\] an array of strings, formatted according to the `format` parameter.
