Globally change Colors and Text with Adobe Illustrator

In vector maps, as in Maptorian, the layers of text labels are usually very numerous. Editing these layers of text labels is very simple, especially if you want to do it in large sets. First we will select in the layers panel the one we want to edit. Once all the objects in that layer are selected, all you have to do is change the options for all the labels at once by simply changing the parameters in the text properties panel. But, why not use the text styles? The next video (really interesting) shows how to edit text using these styles, which are a very useful tool.
