For example, say I create a notebook with a cell
a = 5 + 2
and then I close Mathematica, reopen the notebook, enter a new cell
b = a*2
and evaluate the new cell with Shift+Enter. I want the output to be 14 without evaluating to evaluate the first cell. Is this posible?
I want this because i'm making a Stylesheet Creator and i have ColorSelectors, inputfield, etc and i want to have dafault values.
