Or is there a better way to do something like this?

It depends on what you want to do. You can create a buffer command:

\def\startamode{\grabbufferdata[amode][startamode][stopamode]} %\def\stopamode {\getbuffer[amode]}

\starttext

All modes. \startamode “A” mode. \stopamode

\stoptext

Thanks, it worked. One question: is there any difference between

\def\starta{...} \def\stopa{...}

and

\definestartstop[a][before={...},after={…}]

Yes because in my definition for \startamode I start a buffer which reads everything untill the delimiting \stopamode and stores it in memory, afterwards you can access the stored content with \getbuffer[…]. When you use \definestartstop to create the environment you have only two commands which perform a few things at the begin and end of the environment but you can do much with the content itself, the only way to gobble the content is to store it in a box but than the buffer method is easier.
