# [Maxima] Missing or deleted entries in documentation

Hello,
A few years ago, I created a few automated procedures for writing some limit questions
for a calculus course.  I remember going through difficulty getting simplification, evaluation and TeX output to work the way I wanted.  Recently I wanted to do something similar. I notice that something I found in the manual before is now gone or maybe I just found this info online somewhere.

Turning on/off simplification
simp:false, simp:true.

This turned out to be very useful to generate the TeX output I was looking for.
Why isn't it in the manual or index or ?  I took me quite a while to rediscover this.

In addition, I found that the new version of wxmaxima 5.19.2 will copy LaTeX but there is no command that I can find to output LaTeX to a file (which I need).  But apparently the capability is there somewhere because I can right click on the expression and copy LaTeX.  Here is a simple
example.
/* [wxMaxima: input   start ] */
tex(x/2)\$ x/2;
/* [wxMaxima: input   end   ] */
$${{x}\over{2}}$$
x/2

The output is in TeX but if I right click on x/2 and copy to LaTeX, I get $$\frac{x}{2}$$,   the LaTeX expression!  Is there a command I can use for this so I can copy it to a file?  latex(x/2) does not work. The LaTeX expression (vs TeX) turns out to be more compatible with online posting of my quiz questions.

Best,
Tim
