The real heart is that if you tap `f6 when in `text , CoSy executes
the line you are on in K and assigns any result to `r .

Everything else has just been built by writing and `f6ing and
and rewriting and ref6ing lines til they do what I think I want .

Great . Now you can work down thru those examples in `text .
You will find a simple example of editing a multi-line fn just
by formatting and displaying it in `.r and editing it there .

.r : VM @ $ f / Display the function `save in `r . edit it .
f : . MV .r / after editing , redefine .

Woops , I generalized `MV to work with delimiters other than
newline "\n" .

Needs to be
f : . MV[ "\n" ] .r / after editing , redefine .
or
f : . MVn .r / after editing , redefine .

Yea , best to have the PDF K Reference Manual available to decipher
the sentences making up CoSy .

If you look at the boot script , /CoSy/kboot.k ( execute :
0: "/CoSy/kboot.k" / )
You see the \m settings of the font . You can try to improve on
my settings .
( The example of reading and editing the boot script is in the initial
.CoSy.text , but I see it says "/CoSy/kboot.txt" instead of
"/CoSy/kboot.k" . It will be fixed in the next release , mid September . )

When you have entered a line for editing , the cursor does become a nearly
unnoticeable skinny vertical line . Often to find it , I up-arrow or
down-arrow to highlight a neighboring line to find where I was .

Arthur has said that he has not worked on the GUI since `95 . Perhaps
with more use , there will be motivation to revisit this aspect of K .

CoSy.csd is a K data file , not even close to text .
In the examples in `text , is :

.r : ( Q ; ( ~ Q ) @\: `h ; .:' Q : sort fns _d ) / fns w help if any .

which will display a table of all the functions with help and definitions .
You can hit Alt PrintScreen to capture it as an image .
I need to make a simple table to text converter so such things can be
output to -.txt files easily .

Start by executing , `f6ing , each of the example lines in the `text
window .

I've just added the following as the first example to execute

1 - 2 / Tap the f6 key to execute this line . note what happened
/ to `l and `r .
/ Tap f5 . See it inserts r in the text .

If you mean by applications things like ledgers an mail-lists , basic
templates or prototypes are included as objects in .CoSy .
No script has ever existed to create them . See down toward
the end of the examples . Generally you can just f6 the names
of any items to see their innards .

Thanks for the great feedback . It is only with it that I can know
the edges which most need sanding and polishing .
