Can't find function names to call

I want to remap a couple of functions but can't find their names.

Example: **Checkbox Toggle** is `<leader>cc`
I want: `<S-Insert>`
If I do: `map <S-Insert> <leader>cc` and use it where `<leader>cc` works, I get
`org_list_unordered xxx links to Identifier`

What do I do? I thought calling the toggle function directly, but I can't find its name.
