2) what is the instruction for tab in scheme code ?

The standard way to find out the Scheme code for a TeXmacs _expression_ is to copy it "as TeXmacs Scheme" (menu Edit -> Copy to -> TeXmacs Scheme). I do not grasp how the code you would like to have should look like, but there is another way as well to compose a macro: write a sample of what you want, copy it, and paste it in source mode. After this you would have to substitute variables for the parts of the context which you want to vary :-)

In this case maybe a combination of the two ways of composing macros could also help.

I have not been able to reproduce your example (the one starting with "die Funtkion") so I cannot paste the corresponding code in this message.
