Hi Vincent,

One trick that you may wish to use to produce diagonal arrows
is to turn a long arrow by 45 or -45 degrees.
Arrows of arbitrary lengths can be obtained by entering them
directly as symbols.  Using the Emacs-look and feel,
this is done as follows:

   C-q rubber-rightarrow-25 return

Next, you may select this arrow and use

   Format -> Transform -> Rotate

I would then put the result inside a macro and
create a keyboard shortcut for it.

Best wishes, --Joris

hi all
as i need all the day to create such tables
i have found this model
lines with fix-horizontal-width tables
ideed it is very simple

now, my aim would be to create it by code, so that i can put a shortcut in my-init-texmacs to have it soon as i need it
i want to say that i ask not that for my personal usage only
my aim is, when i have endly what i want, to share it with french highschool maths teachers on the forums where i am
and the way to share it will be so send them my file my-init-texmacs
i could also spend time to learn how to do the code it but i am absolutely not intersted in i confess
if for colleagues among you it can be a bit not toomuchtime, that can be wonderful, as for many shortcuts i receive on this forum since months

the explanations are in the tm file :
- one centered table with three lines containing each, say, 5 fix-horizontal-width tables (say, 1.3cm)
- indeed, that's all

i really wonder why i have not found this solution before…

thanks for your attention !
