I hope you can help me. I want to use the tab index to navigate through a web page (travel option by option). I want you to print in console the text of the option in which you are. I hope you can understand me and help me. Come out.

This code in jquery could help you, the keyup function is used:

$(window).keyup(function (e) {
  var $focused = $(':focus'); 
  // OTRAS OPCIONES PODRIAN SER:
  // $focused.attr('class')
  // $focused.attr('id')...
  console.log(", "+$focused.prop("tagName")+", "+$focused.text() );
});

Using JS:

document.addEventListener('focus',function(e){
console.log("Elemento: "+document.activeElement.tagName
					+", "+document.activeElement.innerHTML);
}, true);

If using jQuery is an option, you can use .focus() along with .attr() as follows below:

$('#mb1 *').focus(function() {
    console.log($(this).attr('tabindex'));
});

                <li id="sans-serif" tabindex="1.2">Sans-serif</li>
