Deoplete.nvim: How to move and select suggested autocompletion?

[malteneuss]

I cannot walk up or down the list of autocompletions
and i cannot select any specific autocompletion to be inserted.
I believe that some key mappings are missing.
Could you maybe add an example to this project's front page on how to map deoplete actions to its default insert mode keys.

Btw, i have the initialization setting in my init.vim
let g:deoplete#enable_at_startup = 1
and i get a list of suggested autocompletions.

take this

inoremap <silent> <CR> <C-r>=<SID>my_cr_function()<CR>
function! s:my_cr_function()
    return (pumvisible() ? "\<C-y>" : "" ) . "\<CR>"
endfunction
inoremap <expr><TAB>  pumvisible() ? "\<C-n>" : "\<TAB>"
