@ -114,6 +114,19 @@ The following readline key bindings should also work as expected.
If you enable multi-select mode with `-m` option, you can select multiple items
with TAB or Shift-TAB key.
### Extended mode
With `-x` or `--extended` option, fzf will start in "extended mode".
In extended mode, you can specify multiple patterns delimited by spaces, such as: `^music .mp3$ sbtrkt !rmx`
| Token | Description | Match type |
| -------- | ----------------------------- | -------------------- |
| `^music` | Items that start with `music` | prefix-exact-match |
| `.mp3$` | Items that end with `.mp3` | suffix-exact-match |
| `sbtrkt` | Items that match `sbtrkt` | fuzzy-match |
| `!rmx` | Items that do not match `rmx` | invert-fuzzy-match |
Usage as Vim plugin
-------------------
