This key is supposed to bring up the Factoriopedia. It's wired into everything.
Could you please change the default keypress for setting up a temporary request to something else?

I thought about it when I also started to play space age. Problem is that this mod needs three separate modifier to work fully. So unless Windows key is supported I don't know what should replace Alt. Any ideas?

Personally, I changed it to:
Control + Shift + Left-click for "Increase clicked prototype by one"
Control + Shift + Right-click for "Increase clicked prototype by five"
Control + Alt + Left-click for "Increase by recipe ingredients"
Control + Alt + Right-click for "Increase by 5 recipes worth"

It's super important that the factoriopedia be accessible as that's a huge part of the game now.

Ok, I'll think about it and probably include it with next update, thanks.

Done in 2.1.0

Thank you very much for this change, could you add these keys in the mod description?

Done, thanks
