Copy input and User Defined Variables

Hello I'm new to Mathematica. I have two questions Q1: Is there any shortcut for copying the previos input. In MatLab you hit the arrow-up key and voila. I know that you can use % but that is reffering to the output not input. I want a copy of my *input* so I can change it. I do not want to go back to my previos input and change that since I want a new fresh copy of the input. I know of course that you can copy and paste but that takes to much time. Q2: I want to see all the symbols I have defined myself. If I enter ?* I get a list of all the symbols in Mathematica and at the end I see my symbols. But I only want to see my symbols and not Mathematicas. Is there a way to accomplish that? Bubba
