I have a question about the usage of "go down" in this dictionary:
It all goes down in her notebook.
I was thinking this sense of "go down" should be used with "in history", not "in a notebook". Do native speakers think that the example sentence is weird?
From the site you provided a link to in your question:
go down (in something) to be written in something; to be recorded or remembered in something
This use of go down does not have to be paired with (in) history. Native speakers would not find your example sentence (or similar sentences that use go down in the same way) weird.
go down in history as is an idiomatic phrase which is used in the certain context, of course, this phrase is very popular. go down in her notebook is another phrase which is used in another context, and has a different meaning.
go down in has many words which can go after. Some examples from the BNC (British National Corpus):
go down in posterity
go down in value
go down in television
go down in summer
go down in London
go down in size
go down in colour
Which car did Nigel go down in on the Thursday?
I think this "It all goes down in her notebook" is modelled after "to put something down on paper".
The phrase go down has many uses where go is a shortened form of an expression to replace several different verbs, but the action always involves movement and down can be used metaphorically to show direction
In your example
