Mappings
|
||||
--------
|
||||
|
||||
| Mapping | Description |
|
||||
| --- | --- |
|
||||
| `<plug>(fzf-complete-word)` | `cat /usr/share/dict/words` |
|
||||
| `<plug>(fzf-complete-path)` | Path completion using `find` (file + dir) |
|
||||
| `<plug>(fzf-complete-file)` | File completion using `find` |
|
||||
| `<plug>(fzf-complete-file-ag)` | File completion using `ag` |
|
||||
|
||||
### Usage
|
||||
|
||||
```vim
|
||||
imap <c-x><c-k> <plug>(fzf-complete-word)
|
||||
imap <c-x><c-f> <plug>(fzf-complete-path)
|
||||
imap <c-x><c-j> <plug>(fzf-complete-file-ag)
|
||||
```
|
||||
|
||||
### Completion helper
|
||||
|
||||
`fzf#complete` is a helper function for creating custom fuzzy completion using
|
||||
fzf. If the first parameter is a command string or a Vim list, it will be used
