Thank you, I love this. Along with David's suggestion, it shows to me once again the typical cycle of an idea that often at first tends to think way more complicated and it gets simpler every iteration of retouching it. My initial thought was actually to patch luatex to create a new command to wait for a signal, and then felt proud of the follow-up idea it could be offloaded to Lua scripting. Then Davids was a serious simplification of that again and yours is even better :) - Axel
