Confession time: I don't read the Arielle posts anywhere near as thoroughly as GM posts. So if you're sticking important info in there, I'm liable to miss it.
I've been in 2 FATE based games via pbp and don't know what keywords you're referring to, unless it's the conditions placed on a scene by a player. The conditions are generally highlighted to help us notice that they have an affect on our gameplay.
I find myself recapitulating a LOT as a GM. Once posting slows, I have started doing a brief scene description with some action that draws PC attention towards the item in question, or ask specific OOC questions about things they haven't discussed. For the shutter, it might be noise drifting in, then a question about security for the night - watches, doors locked/blocked, and shutter open/closed. Kind of housekeeping things but include the important stuff in there without making a huge deal of it.
Hope this helps. :/
