Defaults scripts are pre-created and compiled scripts written by the Bethesda developers, made with the intention of saving the time of a modder spent writing scripts to perform common tasks. They can be added to any record by going to Scripts>Add, filtering by "default" and choosing one of the scripts to add. Often, they contain properties that should be filled in order for the script to function properly.
===========
I've created an entire list of every single default script in the vanilla game, with definitions of what every single one (180 of them) do. Almost all of them include examples of how the script could be used.
I did approximately 170 of them in the past 2 days, since I was bored and felt like doing something productive. I opened every script as well as checking comments and the name to figure out what each did. There were 3 I didn't understand and several redundant scripts, though I provided definitions for some.
Thanks to exit, Paulibobo and Himeki for help on a few definitions (exit did about 10), and examples.
Since it's on the Wiki, the intention is that it will be improved. Hopefully it'll be helpful to some of ye scripters out there.
