Hi @elprofejimenez,

You can show or hide the various items on the left-hand menu, as shown in the  How do I manage Course Navigation links? - Instructure Community - 1020  guide.  You can't really change the names of existing menu items though.

One "hack" for this is to use the external app "redirect tool" to add a menu item with a custom name, but as a Canvas admin, I generally don't recommend doing that as those menu items would break when doing a course import in the future and oftentimes confuse students more than help them, especially when they are in multiple courses and expect similar menus and functionality in the courses.  This is, of course, my own opinion, so you're free to experiment with this on your own.

Hope this info helps!
