It's easy to read the steps from Rubi, but kind of tired to copy it out of as $\LaTeX$. That's what now I do:
Int[x Sin[x], x]//Steps
For example,click one step, then paste it to .nb, then //TeXForm to get the TeX code. (kind of monkey job)
I've tried FullForm, get nothing,
// Trace gives back a lot of things, which seems a bit hard for me to pick out what I want. So I want a "automatical" way to do this.
