AC Question

I accidently hid the menu within my app drawer. After clicking on the app drawer, the little grid of dots, all my apps would come up and at the top of the screen there was a bar with a menu. The menu had options to hide and unhide apps, also to hide that menu bar. I accidently hit the hide menu button and now i dont know how to unhide it!! Please help! I have hidden apps i cant get to now. I cant find imformation on this subject ANYWHERE.
