Unite.vim preview navigation

Question

I'm using Vim with the Unite plugin. How to prevent jump to first line in unite preview, when cursor is in last position and key down J is pressed and otherwise jump from first line to last line, when key up K is pressed?

Answer 1

Not too hard, given the Unite docs. Lines for your vimrc:

augroup my_unite
    autocmd!
    autocmd FileType unite call s:unite_my_settings()
augroup END

function! s:unite_my_settings()
    nmap <buffer><expr> j line('.') == line('$') ? '' : '<Plug>(unite_loop_cursor_down)'
    nmap <buffer><expr> k line('.') == 1 ? '' : '<Plug>(unite_loop_cursor_up)'
endfunction

Answer 2

You can find out if there is a mapping on your J by typing

:map j

If there is, and you do not like, you can unmap it by putting this into your vimrc

autocmd VimEnter * unmap j

It should do the trick (the same for the K).

There is also another way (:help after-directory) but I prefer this one.
