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
