Hello, it seems that \starthiding ... \stophiding dislikes \doifmode scope. The following code fails: ---- \enablemode[A] \starttext Hello \starthiding Don't show me %\stophiding \doifmode{A} { Aaa \starthiding Don't show me %\stophiding } World \stoptext ---- On the contrary, the following code is OK: ---- \enablemode[A] \starttext Hello \starthiding Don't show me %\stophiding \doifmode{A} { Aaa } World \stoptext ---- So, should I deduce that \starthiding ... \stophiding block cannot be used inside \doifmode (and family)?
