It is possible to do it with a style file, to load, or it is also possible within the same document, to test things quickly: from the menu: tools, macros, edit preamble (not edit macros, I am not able to get that to work as well!), and then again deselect edit preamble to go back to normal editing.

I used the following guide for writing macros:

http://www.texmacs.org/Tutorial/Editing/Chapter4.html

and some help from this too:

and I have to fight a bit too because I can't get everything straight at the first attempt; but eventually it works :-)

The definition with the style file has worked more promptly than the definition using the "edit preamble" menu item.

Thanks all for your solutions, I will try them out. To be honest I have
never defined my own macros so I have first to learn how to define
them. Am I correct that I first have to define my own style file to
define a macro? I saw in tools a macro editor but I could not use it to
define the eqref macro.

Thanks in advance

As for the first question. I did a small research, relevant macros to
the handling of lists and enumerations are contained in 

TeXmacs/packages/standard/std-list.ts

in particular a new counter is defined via

<new-counter|item>

which in turn defines a series of macros to handle the counter like
<reset-item>
<the-item>
<inc-item>

if you want to reset the counter at an arbitrary number, you have to
add this at the beginning of the new environment

<assign|<counter-item>|10>

for example. Note that this has to really be at the beginning of the
enumerate environment, in particular before the first item.

Note also that <counter-item> is a macro which returns the name of
the variable which contains the counter.

I know one way of getting what you want for the second question,
but it is not completely automatic.

You can define and load the following macro:


<assign|eqref|<macro|lab|Equation <reference|<arg|lab>>>>

(and similar ones for theorems, propositions and so on)

and use it in place of the \reference macro. The advantange of
using \eqref with respect to typing everytime "Equation \reference"
is that it will ensure consistent formatting.

I suspect there is a way to write a macro to automatically
recognize the type of reference and format it according to type,
like the cleveref package for LaTeX, but - at least for now - it is
too complicated for me to figure it out.

Hello,
	I have two questions concerning TexMacs. The first is about the
numbering of enumeration list, when I insert a enumeration it
always
start at 1, a, i etc. Is it possible to specify the start
numbering at
a different number.
	The second is of the numbering of references. When you insert a
label for a theorem, proposition etc  or a displayed formula and
reference to it the references used the same x.y format for both.
So
sometimes you have to confusion that for example a reference
displays
the same number (for example 10.14) but in one case it refers to
a
theorem and in the other case it references to a displayed
formula. You
can not seen the difference. Is it somehow possible to display
for the
reference to display 'eq 10.14' if it refers to a displayed
formula and
 'theorem 10.14' if it refers to a theorem (and likewise for
lemmas,
propositions ...).
	I searched in the manual but could not found a way to do this
two things.

Thanks in advance for a possible answer and also for a excellent
math
editor.
