Ok, so im at a part in the main quest where i need to talk to davayth fyr and he wants the dwemer coherer cosades gives ya. Well i try to to offer it to him as a gift or i show it and pull it back doesnt matter which i select, it just adds in the coversation window him asking about it again with the same two available responses. What i need to know what is the console command to add journal entries, what is the command for this event in particular, aaaaaaannnd if something similar should happen again where can i find the command for that. I did a search because i remember seeing something similar years ago but came up with nothing relevant now.

It's all here:
