OK, I'm not using an American keyboard but I tried every key with no results. Some European care to enlighten me? How can I activate the console? Do I have to modify the configuration file first?To trigger the egg icon, hit the Ctrl key, the Shift key and the ~ key. On some keyboards in other countries, you have to click something other than the ~ key. I'm not sure what.
EDIT: Thanks to Santi I solved the problem. From the Start Bar, I changed the default configuration of my keyboard from Italian to American (United States), and this symbol [\] was magically
substituted by this one [~], thus allowing me to activate the easter eggs. I nonetheless leave the thread here, just in case another fellow European has the same problem
