unity help with apps

[Hank Smith]

Hello when going threw the list of apps I go to windows key
home
apps
hit enter
I am only seeing a hand full of apps.
there isn't much that I am able to see how do I get to the different 
catagories of apps? etc?
I did the following:
down arrow to the home button, right arrow to the applications button, press
ENTER, use the 4 arrows to explore the installed apps; they are in
categories, so pressing enter on a button opens a new tile of applications.

I am only seeing stuff like sound recorder and stuff like that not 
actual catagories, and the number of apps seems hardly any am confused.
