@ -276,34 +276,17 @@ If you have set up fzf for Vim, `:FZF` command will be added.
" With options
:FZF --no-sort -m /tmp
" Bang version starts in fullscreen instead of using tmux pane or Neovim split
:FZF!
```
Similarly to [ctrlp.vim](https://github.com/kien/ctrlp.vim), use enter key,
`CTRL-T`, `CTRL-X` or `CTRL-V` to open selected files in the current window,
in new tabs, in horizontal splits, or in vertical splits respectively.
Note that the environment variables `FZF_DEFAULT_COMMAND` and `FZF_DEFAULT_OPTS`
also apply here.
If you're on a tmux session or using Neovim, `:FZF` will launch fzf in a
split-window whose height can be adjusted with `g:fzf_height` (default:
'40%'). However, the bang version (`:FZF!`) will always start in fullscreen.
In GVim, you need an external terminal emulator to start fzf with. `xterm`
command is used by default, but you can customize it with `g:fzf_launcher`.
```vim
" This is the default. %s is replaced with fzf command
let g:fzf_launcher = 'xterm -e bash -ic %s'
" Use urxvt instead
let g:fzf_launcher = 'urxvt -geometry 120x30 -e sh -c %s'
```
If you're running MacVim on OSX, I recommend you to use iTerm2 as the launcher.
Refer to the [this wiki
page](https://github.com/junegunn/fzf/wiki/On-MacVim-with-iTerm2) to see how
to set up.
Note that the environment variables `FZF_DEFAULT_COMMAND` and
`FZF_DEFAULT_OPTS` also apply here.
#### `fzf#run([options])`
