## Changing the layout

The key bindings use `--height 40%` option to display fzf finder below your cursor, but it's configurable.

If you prefer to run fzf in full screen mode, add `--no-height` to your `$FZF_DEFAULT_OPTS` like follows:

export FZF_DEFAULT_OPTS='--no-height --no-reverse'


Or if you prefer to start in a tmux split pane, set `$FZF_TMUX` to `1`.

export FZF_TMUX=1


## `CTRL-T`

### Preview

You can preview the content of the file under the cursor by setting `--preview` option.

Using highlight (http://www.andre-simon.de/doku/highlight/en/highlight.html)

export FZF_CTRL_T_OPTS="--preview '(highlight -O ansi -l {} 2> /dev/null || cat {} || tree -C {}) 2> /dev/null | head -200'"


### Using `--select-1` and/or `--exit-0`

export FZF_CTRL_T_OPTS="--select-1 --exit-0"


`--select-1` automatically selects the item if there's only one so that you don't have to press enter key. Likewise, `--exit-0` automatically exits when the list is empty. These options are also useful in `FZF_ALT_C_OPTS`.

## `CTRL-R`

### Sorting and exact matching

Sorting is disabled by default to respect chronological ordering. You can dynamically enable sorting by pressing `CTRL-R` again, but if you like it to be enabled by default, add `--sort` to `FZF_CTRL_R_OPTS`. Likewise, if you prefer to use exact (non-fuzzy) matching, add `--exact`.

export FZF_CTRL_R_OPTS='--sort --exact'


### Full command on preview window

Commands that are too long are not fully visible on screen. We can use `--preview` option to display the full command on the preview window. In the following example, we bind `?` key for toggling the preview window.

export FZF_CTRL_R_OPTS="--preview 'echo {}' --preview-window down:3:hidden:wrap --bind '?:toggle-preview'"


### Directly executing the command (CTRL-X CTRL-R)

#### zsh

fzf-history-widget-accept() {

fzf-history-widget

zle accept-line

}

zle -N fzf-history-widget-accept

bindkey '^X^R' fzf-history-widget-accept


#### bash

bind "$(bind -s | grep '^"\\C-r"' | sed 's/"/"\\C-x/' | sed 's/"$/\\C-m"/')"


### Dynamically choose to execute or edit

There is an open issue for this; [#477](https://github.com/junegunn/fzf/issues/477). We have a solution for zsh, but not for bash.

## `ALT-C`

### Preview

The following example uses `tree` command to show the entries of the directory.

export FZF_ALT_C_OPTS="--preview 'tree -C {} | head -200'"
