How to custom my keymaps

[CaesarLi-WantToBeAFreeMan]

Hi everybody,
I viewed docs, but I cannot find how to keymap:

[d -> go to previous directory
]d -> go to next directory
K -> go to first node
J -> go to last node
<C-b> -> scroll up 10 nodes or first node
<C-f> -> scroll down 10 nodes or last node
<C-u> -> scroll up 5 nodes or first node
<C-d> -> scroll down 5 nodes or last node
= -> toggle full screen
...

btw this is my neo-tree keymap configuration:

            --fuzzy search
            ["#"]               = {"fuzzy_sorter",              desc = "sort nodes using fuzzy matching"},
