Very cool, thanks for sharing. I would note, that one nice thing about
embedded mode is that there is no need for the #+begin/end_src calc
blocks, rather the formulas may be placed directly in the Org-mode file.
So to re-write a small portion of your previous example...

#+Title: Emacs Calc Embedded Mode Examples
* Temperature Conversion (solving equations)
Conversion from Celsius to Fahrenheit involves multiplication by 1.8
and the addition of 32 as shown below.
eq := f = 1.8 c + 32
Solving for Celsius from Fahrenheit is then.
ceq := solve(eq, c) =>
So, if we know that water boils at 100\deg Celsius, we can find the
boiling point of water in Fahrenheit.
subst(eq, c, 100) =>
Or if we know that paper burns at 451\deg Fahrenheit, we can find the
burning point of paper in Celsius.
subst(ceq, f, 451) =>

Using embedded mode is still fairly awkward for me. I would benefit
greatly from some sort of quick reference card explaining the key
bindings and maybe an easier way to switch to/from embedded mode.

I'm not clear on how the even/odd example works in calc, could you share
a link to the specific manual page you're referencing? I've long felt
that calc would be a *very* powerful tool, if only I could climb the
learning curve.
