You have to substitute the following

(define (export-to-proposed-pdf)
  (wrapped-print-to-file (propose-pdf-name)))

for the function (export-to-proposed-pdf) defined in the snippet you 
took from the linked post.

Please give me some time :-)

For one of the things you asked though

> - remapping all the existing shortcuts

you can take a look at section 12.4 of the manual together with the 
example in the snippet you took from the post, which I copy here:

(kbd-map ("M-e p" (export-to-proposed-pdf)))

Please experiment a bit and maybe write again. I think that it is 
important that you experiment a bit with this because in this case I 
think it is the only way to become able to  use it.
In the key combination keys need to be separated by spaces (so pressing 
x twice is "x x").  A represents the alt key, C ctrl, S shift and M 
represents the meta key (in many keyboard setups it is the esc key, 
which needs to be pressed before the key it modifies, not simultaneously).
Moreover that if your key combination is interpreted ("intercepted") by 
the OS then it does not get input into TeXmacs and therefore the 
shortcut does not work. For example you can assign an action to 
shift-tab, but not to shift-p, because the latter would be interpreted 
as a capital p by the OS and so TeXmacs would not see "S-p" but "P" (I 
hope that I am getting this right ;-) ).

Finally (but you can consider this after you have experimented a bit) if 
the keyboard shortcut is defined in the TeXmacs default and loaded 
lazily, then the default definition would overwrite the one that you 
defined in my-texmacs-init.scm.
To make sure that this does not happen, you have to force the loading of 
default definitions before you set up yours. Please look at 
http://forum.texmacs.cn/t/change-systems-default-shortcut-for-symbols/310/14 
for how to do it.

If you look at the kbd-map forms in progs/generic/generic-kbd.scm you 
could get some inspiration. Also here is a list of places where keyboard 
shortcuts are defined in TeXmacs: 
http://forum.texmacs.cn/t/quick-way-to-check-keyboard-shortcuts/87/3, 
maybe there should be an easier way to get all of the existing shortcuts 
(rather than through a program to search text).

For the other two questions:

> - creating new items in "insert/énoncé"

please give me more time, in the meantime you can read section 12.3 of 
the manual (but I agree that a description which is paced more slowly 
could help). I should be able to write it up in a short time (I would 
add one or two examples to the ones already present in the manual).

> - modifying the format of these items (definition in italic or no etc…)

my feeling is that either you get instructions for the effects that you 
want, but in this case the effort of generalizing those to all 
formatting rests completely on you, or you need to wait till someone 
writes a tutorial, which will take some time. Maybe I can write a 
tutorial limited to simple formatting (I do not have a grasp of the 
macros that is general enough to write a general tutorial), but not 
immediately.
By the way on this topic I have the feeling that in the tutorial one 
needs to convey the idea that one is addressing a limited set of the 
TeXmacs macro programming, and that the readers need to put in a little 
bit of intuition to figure out when what he is reading does *not* apply 
to the things that they would like to accomplish.
