lists let me having natural automatic numerotations

i also know approximatively how to make a list to start to any choosen number, say 4, or a variable.

now, my question is : how to have an automatic numerotation of items, independantly of any natural formatting of TeXmacs, i.e. independantly of sections, lists etc.

for example

1. lets have a demonstration of this

2. blabla

blabla

blabla

3. theorem : this and this

4. notice that if you have read 2. etc

without any include->enumeration of section

do you have an idea how to do this ?
