Open telescope when you type "telescope"

app.js

function openInNewTab(url) {
    const win = window.open(url, '_blank');
    win.focus();
}

const pattern = ['t', 'e', 'l', 'e', 's', 'c', 'o', 'p', 'e'];
let current = 0;

const keyHandler = (event) => {
    // If the key isn't in the pattern, or isn't the current key in the pattern, reset
    if (pattern.indexOf(event.key) < 0 || event.key !== pattern[current]) {
        current = 0;
        return;
    }

    // Update how much of the pattern is complete
    current++;

    // If complete, alert and reset
    if (pattern.length === current) {
        current = 0;
        openInNewTab('/telescope');
    }
};

// Listen for keydown events
document.addEventListener('keydown', keyHandler, false);
