I am writing notes for my teaching and would like to do the following with modes:

* If the file is compiled with context file.tex then everything (i.e. the content in all modes) is typeset.

* If the file is compiled with context --mode=test1 file.tex then only mode test1 is typeset.

I do not see how to do this easily. The example I am working on looks like this:

%%% file.tex

%%%

This, however, naturally gives not output, since the modes test1 and test2 are not activated. If I compile with context --mode=test1 file.tex I get the content in mode test1, as I want.

I have tried to change "keep" to "yes" in the setup of the modes, but then the material in both modes are typeset no matter what command flag I use.

Do I miss something?

PS In reality I have about 25 lectures, so using this method there will be about 25 modes in total.
