How to add a free information layer in the [top|bottom] toolbar?
I have a document containing many forward slashes (/). I noticed that ConTeXt does not allow breaks after /. For instance, if a text contains bear/rabbit/tiger, it will not place a break and the text will flow off the edge into the margins.


How can I create a special environment, inside of which, the rules for line breaking allows a line break after a /, if deemed necessary, with slightly higher or equal preference to what is given to a space?
