# [NTG-context] Question on enabling/disabling modes

```Hi!

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
\definemode[test1][keep]
\definemode[test2][keep]
\starttext
\startmode[test1]
We are in mode test1.
\stopmode
\startmode[test2]
We are in mode test2.
\stopmode
\stoptext
%%%

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?
