comment How do I efficiently navigate the command line interface to Mathematica?
@halirutan in fact in Mathematica 9 there are some improvements in this regard. At least some things like cycling through history do work.

Indeed, the old defaults are reproduced by first Plot in my example.

comment How to create a writable and clearable symbol?
I was just interested in creating a usable symbols. I'm well aware of the possibility to use hash maps like fdds[anything]=1.

Please note the PS part of the question, which has been there since the very beginning. I do know I can do this like an array, but I'm interested in symbol-based approach.

comment How to create a writable and clearable symbol?
What would be the principal difference between Symbol and ToExpression here if the latter is used just with one argument? Could I just replace the former with the latter for the first assignment?

comment plotting a trig functions along with its envelope
This way though doesn't seem to catch when the envelope should go to zero. Shouldn't it e.g. vanish near 2?

comment Why do two roots of my equation disappear when I give numerical values to two parameters?
And, when the first two are solutions at all? They seem to be spurious solutions...

In fact, using Simplify[eq/.sol] gives the two Trues, leaving first two equations unevaluated.
