Since WordPress removed the original bookmarklet functionality, I needed to make a plan to restore the functionality in my Chrome browser. Create a new bookmark, right-click, Edit..., paste the code in the URL field. Just replace yoursite.com with your Wordpress URL

Bookmarklet Functionality for WordPress

javascript: var d = document,
    w = window,
    e = w.getSelection,
    k = d.getSelection,
    x = d.selection,
    s = (e ? e() : (k) ? k() : (x ? x.createRange().text : 0)),
    f = 'https://yoursite.com/wp-admin/press-this.php',
    l = d.location,
    e = encodeURIComponent,
    g = f + '?u=' + e(l.href) + '&t=' + e(d.title) + '&s=' + e(s) + '&url-scan-submit=Scan';

function a() {
    if (!w.open(g, 't', 'toolbar=1,resizable=1,scrollbars=1,status=1,left=480,width=960,height=800')) {
        l.href = g;
    }
}
setTimeout(a, 0);
void(0);
