Does the keys also merged just as opts do？ Need a detail explain of how the lazy.nvim merge all the parts?

[cxwx]

Is there an doc for how lazy.nvim merge and run for each options?

{
"A", opts = {...}, keys = {...}, config = {...} ..., dependence = {"B"}, enabled = ..., cond = ...
},
{
"A", opts = {...}, keys = {...}, config = {...} ..., dependence = {"B"}, enabled = ..., cond = ...
},
{
"B", opts = {...}, keys = {...}, config = {...} ..., dependence = {"A"}
}

how are the plugin merge each {} tables? and the A B order?
