Build you own map of keys

import Editor from "granit";

const enterKeyPressed = (record, event) => {
    const newRecord = {...record};
    const stringUntilSelectionStart = newRecord.value.substring(0, newRecord.selectionStart);
    const stringAfterSelectionStart = newRecord.value.substring(newRecord.selectionStart, newRecord.value.length);
    newRecord.value = stringUntilSelectionStart + "\n" + stringAfterSelectionStart;
    newRecord.selectionStart += 1;
    newRecord.selectionEnd += 1;
    return newRecord;
}

const keysMap = {
    "mac+13": enterKeyPressed
};

const lifeCycleMap = {
    "mac+cmd+90": "undo"
}

const highlightString = (text) => {
    const rows = text.split("\n");
    const newRows = rows.map(item => {
        const string = /^[A-Za-z0-9_-]+\s=\s".*"$/;
        const stringMatch = item.match(string);
        if(stringMatch) {
            const splitted = stringMatch[0].split(" = ");
            return `<span class="string">${splitted[0]}</span> = <span class="string">${splitted[1]}</span>`;
        }
        return item;
    });
    return newRows.join('\n');
