So out I went on the net to search for it, where I practically went to the fifth page of the search and found this forum where people ask people on techs. chiafruitguild, a member of the forum, asked the same question I had. Luckily M.Hirsch, another member of the group answered the question!
"Probably there is an additional META-Key, "Fn", that you have to press and hold. Sometimes you have to switch "Num Lock" off. But you should read your notebook's documentation, this depends on your specific model."
I tried all and found out just like chiafruitguild did, it was the fn button! It's situated on next to the ctrl button on the left side of the keyboard. Geez! =Z
