[LE] Skyrim and action script interaction

[nexusMods3]

I am writing to ask if you could give me some pointers on how Skyrim and action script interact with each other. If I wanted to create a mod where I increased the maximum number of items that I can drop without calling the "How Many?" menu(for instance, if I wanted to be able to drop up to 10 items without that menu), what would I need to change? Is it a papyrus script or an action script? Where does this interchange between action script and game data happens? Similarly, if I wanted to change a menu associated with any action, for instance, the menu that shows up when I try to poison a weapon or the menu that shows up when I want to advance time, how would I go about it?

 

Thanks a lot in advance.
