|
|
" Usage:
|
|
" Copy this file to the vim/neovim plugin directory.
|
|
" To open nnn as a file picker in vim/neovim, use the command ":NnnPicker" or
|
|
" ":Np" or the key-binding "<leader>n". Once you select one or more files and
|
|
" quit nnn, vim/neovim will open the first selected file and add the remaining
|
|
" files to the arg list/buffer list. If no file is explicitly selected, the
|
|
" last selected entry is picked.
