## Usage ## Usage
**fzf.kak** doesn't provide any mapping by default. Instead there's now a `fzf-mode` command There's no default key binking to invoke fzf, but **fzf.kak** provides a `fzf-mode` command that can be mapped to preferred key.
which intentionally was made to simplify user mappings. You can set your own mapping to invoke `fzf-mode`:
Each fzf command has mnemonic mapping, like `f` for opening files, `t` for tags and so on. ```
map global normal <c-p> ': fzf-mode<ret>'
In this mode new mappings are available: # note that the space after colon is intentional to suppess fzf-mode to show in command history

### Settings ### Settings
**fzf.kak** features a lot of settings via options that can be altered to change how **fzf.kak** behaves.
#### Tmux
When using inside tmux, fzf will use bottom split. Height of this split can be changed with `fzf_tmux_height` option.
`fzf_tmux_height_file_preview` option is used to control height of the split when you do file searching.
#### Files #### Files

#### Preview Though it is not recommended, since `sort` may slowdown `fzf-tag` on huge projects.
You can turn on the preview window in fzf window by setting `fzf_preview` option to `true`:
```kak ##### Filtering tags
set-option global fzf_preview true Since ctags supports showing particular kind of tag for many languages,
``` `fzf-tag` dinamicly defines mappings for those languages with <kbd>Alt</kbd> key based on current filetype.
For example to show only functions while `fzf-tag` is active press <kbd>Alt</kbd>+<kbd>f</kbd>.
It will reload fzf window and only function tags will be listed.
#### Preview
When using X11 **fzf.kak** automatically tries to detect where to show preview window, depending
on aspect ratio of new termial window. By default if the height is bigger than the width, preview occupies
upper 60% of space. If height is smaller than the width, preview is shown at the right side.
You can configure the amount of space for preview window with these options: `fzf_preview_height` and `fzf_preview_width`.
When **fzf.kak** is used in tmux, it will show preview on the right side. Heigth of preview split can be adjusted with
`fzf_tmux_height_file_preview`
Amount of lines in preview window can be changed with `fzf_preview_lines` option.
You also can specify which highlighter to use within the preview window with `fzf_highlighter` option. You also can specify which highlighter to use within the preview window with `fzf_highlighter` option.
