Say, I have a formula like this (in LaTeX or Maple or other text system):

Result: ((6*(k2+k3))*A123*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2+6*A12*(-k3+k2)*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*(exp(-k2*(k2^2*t-x)))^2+(-(6*(-k3+k2))*A13*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2-(6*(k2+k3))*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*exp(-k2*(k2^2*t-x))

Note: the above formula is only one part of the result of a maple calculation, I just can't break them up because there are so many many terms.

Apparently, It's very hard to read. What I want to do is to fold the matched brackets level by level. If all the brackets are folded, I can find out clearly how many terms there are. Then I can analyze from the top level to the details of every term. But I just don't know how to realize that. Maybe there are some existed software which can visualize this kind of complex formula. Any idea?

P.S. I use Linux system. The open source alternatives are better.
