[fzf-tmux](bin/fzf-tmux) is a bash script that opens fzf in a tmux pane.
```sh
# usage: fzf-tmux [-h [HEIGHT[%]]] [-w [WIDTH[%]]] [--] [FZF OPTIONS]
# usage: fzf-tmux [-u|-d [HEIGHT[%]]] [-l|-r [WIDTH[%]]] [--] [FZF OPTIONS]
# select git branches in horizontal split (15 lines)
git branch | fzf-tmux -h 15
# select git branches in horizontal split below (15 lines)
git branch | fzf-tmux -d 15
# select multiple words in vertical split (20% of screen width)
cat /usr/share/dict/words | fzf-tmux -w 20% --multi
# select multiple words in vertical split on the left (20% of screen width)
cat /usr/share/dict/words | fzf-tmux -l 20% --multi --reverse
```
It will still work even when you're not on tmux, silently ignoring `-h` and
`-w` options, so you can invariably use `fzf-tmux` in your scripts.
