marking rectangles, you can `C-x C-x` to switch point and mark to make changes

+Use calc, it's super-powerful:
 
-[Calc](https://www.gnu.org/software/emacs/manual/html_mono/calc.html) is an 
ancient and powerful calculator in emacs with many capabilities, including 
operating on _matrix_ data.  In addition to simple sums, `SpeedRect` offers 
powerful two-way communication with calc:
+### Using Calc
 
-1. It can send columns of numbers to calc as a _matrix_ (2D array of numbers). 
 Once in calc, you can operate on those numbers using a wide array of 
operations.  Many of these "just work" on matrices (e.g. `1 +` will add one to 
all the numbers).  Others can easily be mapped over matrix elements (try `v 
m`). 
-2. Once you have something you're happy with at the top of calc's *stack* (the 
entry number `1:`), you can:
-    - hit `q` to return to your buffer (where `rectangle-mark-mode` will still 
be active),
-    - adjust the position of your rectangle if needed (`S-left/right` is 
useful for this), and
-    - hit `m` to copy the top calc matrix over the top of the marked 
rectangle, if it has the right number of rows.

 Note: what you see is what you get in calc.  `v [` and `v ,` will remove the 
brackets and commas.  `v >` will right align numbers.  `d f` will let you set 
the number of digits after the decimal.  And many more options.
