You can replace fzf command on each example with fzf-tmux to start fzf in a new tmux split pane.

Opening files

# fe [FUZZY PATTERN] - Open the selected file with the default editor
#   - Bypass fuzzy finder if there's only one match (--select-1)
#   - Exit if there's no match (--exit-0)
fe() {
  local file
  file=$(fzf --query="$1" --select-1 --exit-0)
  [ -n "$file" ] && ${EDITOR:-vim} "$file"
}

# Modified version where you can press
#   - CTRL-O to open with `open` command,
#   - CTRL-E or Enter key to open with the $EDITOR
fo() {
  local out file key
  out=$(fzf-tmux --query="$1" --exit-0 --expect=ctrl-o,ctrl-e)
  key=$(head -1 <<< "$out")
  file=$(head -2 <<< "$out" | tail -1)
  if [ -n "$file" ]; then
    [ "$key" = ctrl-o ] && open "$file" || ${EDITOR:-vim} "$file"
  fi
}

Changing directory

# fd - cd to selected directory
fd() {
  local dir
  dir=$(find ${1:-*} -path '*/\.*' -prune \
                  -o -type d -print 2> /dev/null | fzf +m) &&
  cd "$dir"
}
# fda - including hidden directories
fda() {
  local dir
  dir=$(find ${1:-.} -type d 2> /dev/null | fzf +m) && cd "$dir"
}

Suggested by @harelba and @dimonomid:

# cdf - cd into the directory of the selected file
cdf() {
   local file
   local dir
   file=$(fzf +m -q "$1") && dir=$(dirname "$file") && cd "$dir"
}

Searching file contents

grep --line-buffered --color=never -r "" * | fzf

# with ag - respects .agignore and .gitignore
ag --nobreak --nonumbers --noheading . | fzf

Command history

# fh - repeat history
fh() {
  eval $(([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s --tac | sed 's/ *[0-9]* *//')
}
# fh - repeat history
fh() {
  print -z $(([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s --tac | sed 's/ *[0-9]* *//')
}

Replacing eval with print -z will push the arguments onto the editing buffer stack, allowing you to edit the command before running it. It also means the command you run will appear in your history rather than just fh. Unfortunately this only works for zsh.

With write to terminal capabilities

# utility function used to write the command in the shell
writecmd() {
  perl -e '$TIOCSTI = 0x5412; $l = <STDIN>; $lc = $ARGV[0] eq "-run" ? "\n" : ""; $l =~ s/\s*$/$lc/; map { ioctl STDOUT, $TIOCSTI, $_; } split "", $l;' -- $1
}

# fh - repeat history
fh() {
  ([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s --tac | sed -re 's/^\s*[0-9]+\s*//' | writecmd -run
}

# fhe - repeat history edit
fhe() {
  ([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s --tac | sed -re 's/^\s*[0-9]+\s*//' | writecmd
}

This have been tested in bash.

Processes

# fkill - kill process
fkill() {
  pid=$(ps -ef | sed 1d | fzf -m | awk '{print $2}')

  if [ "x$pid" != "x" ]
  then
    kill -${1:-9} $pid
  fi
}

Git

# fbr - checkout git branch
fbr() {
  local branches branch
  branches=$(git branch) &&
  branch=$(echo "$branches" | fzf +m) &&
  git checkout $(echo "$branch" | sed "s/.* //")
}

# fbr - checkout git branch (including remote branches)
fbr() {
  local branches branch
  branches=$(git branch --all | grep -v HEAD) &&
  branch=$(echo "$branches" |
           fzf-tmux -d $(( 2 + $(wc -l <<< "$branches") )) +m) &&
  git checkout $(echo "$branch" | sed "s/.* //" | sed "s#remotes/[^/]*/##")
}

# fco - checkout git branch/tag
fco() {
  local tags branches target
  tags=$(
    git tag | awk '{print "\x1b[31;1mtag\x1b[m\t" $1}') || return
  branches=$(
    git branch --all | grep -v HEAD             |
    sed "s/.* //"    | sed "s#remotes/[^/]*/##" |
    sort -u          | awk '{print "\x1b[34;1mbranch\x1b[m\t" $1}') || return
  target=$(
    (echo "$tags"; echo "$branches") |
    fzf-tmux -l30 -- --no-hscroll --ansi +m -d "\t" -n 2) || return
  git checkout $(echo "$target" | awk '{print $2}')
}
# fcoc - checkout git commit
fcoc() {
  local commits commit
  commits=$(git log --pretty=oneline --abbrev-commit --reverse) &&
  commit=$(echo "$commits" | fzf --tac +s +m -e) &&
  git checkout $(echo "$commit" | sed "s/ .*//")
}
# fshow - git commit browser
fshow() {
  local out sha q
  while out=$(
      git log --decorate=short --graph --oneline --color=always |
      fzf --ansi --multi --no-sort --reverse --query="$q" --print-query); do
    q=$(head -1 <<< "$out")
    while read sha; do
      [ -n "$sha" ] && git show --color=always $sha | less -R
    done < <(sed '1d;s/^[^a-z0-9]*//;/^$/d' <<< "$out" | awk '{print $1}')
  done
}
# fc - get git commit sha
# example usage: git rebase -i `fc`
fc() {
  local commits commit
  commits=$(git log --color=always --pretty=oneline --abbrev-commit --reverse) &&
  commit=$(echo "$commits" | fzf --tac +s +m -e --ansi --reverse) &&
  echo -n $(echo "$commit" | sed "s/ .*//")
}

Tags

# ftags - search ctags
ftags() {
  local line
  [ -e tags ] &&
  line=$(
    awk 'BEGIN { FS="\t" } !/^!/ {print toupper($4)"\t"$1"\t"$2"\t"$3}' tags |
    cut -c1-80 | fzf --nth=1,2
  ) && $EDITOR $(cut -f3 <<< "$line") -c "set nocst" \
                                      -c "silent tag $(cut -f2 <<< "$line")"
}

tmux

# fs [FUZZY PATTERN] - Select selected tmux session
#   - Bypass fuzzy finder if there's only one match (--select-1)
#   - Exit if there's no match (--exit-0)
fs() {
  local session
  session=$(tmux list-sessions -F "#{session_name}" | \
    fzf --query="$1" --select-1 --exit-0) &&
  tmux switch-client -t "$session"
}
# ftpane - switch pane
ftpane () {
  local panes current_window target target_window target_pane
  panes=$(tmux list-panes -s -F '#I:#P - #{pane_current_path} #{pane_current_command}')
  current_window=$(tmux display-message  -p '#I')

  target=$(echo "$panes" | fzf) || return

  target_window=$(echo $target | awk 'BEGIN{FS=":|-"} {print$1}')
  target_pane=$(echo $target | awk 'BEGIN{FS=":|-"} {print$2}' | cut -c 1)

  if [[ $current_window -eq $target_window ]]; then
    tmux select-pane -t ${target_window}.${target_pane}
  else
    tmux select-pane -t ${target_window}.${target_pane} &&
    tmux select-window -t $target_window
  fi
}

v

Inspired by v. Opens files in ~/.viminfo

# v - open files in ~/.viminfo
v() {
  local files
  files=$(grep '^>' ~/.viminfo | cut -c3- |
          while read line; do
            [ -f "${line/\~/$HOME}" ] && echo "$line"
          done | fzf-tmux -d -m -q "$*" -1) && vim ${files//\~/$HOME}
}

z

Integration with z, like normal z when used with arguments but displays an fzf prompt when used without.

unalias z 2> /dev/null
z() {
  if [[ -z "$*" ]]; then
    cd "$(_z -l 2>&1 | fzf +s --tac | sed 's/^[0-9,.]* *//')"
  else
    _z "$@"
  fi
}

Here is another version that also supports relaunching z with the arguments for the previous command as the default input by using zz

unalias z
z() {
  if [[ -z "$*" ]]; then
    cd "$(_z -l 2>&1 | fzf +s --tac | sed 's/^[0-9,.]* *//')"
  else
    _last_z_args="$@"
    _z "$@"
  fi
}

zz() {
  cd "$(_z -l 2>&1 | sed 's/^[0-9,.]* *//' | fzf -q $_last_z_args)"
}

Since z is not very optimal located on a qwerty keyboard I have these aliased as j and jj

alias j=z
alias jj=zz

Google Chrome (OS X)

Browsing history

# c - browse chrome history
c() {
  local cols sep
  cols=$(( COLUMNS / 3 ))
  sep='{{::}}'

  # Copy History DB to circumvent the lock
  # - See http://stackoverflow.com/questions/8936878 for the file path
  cp -f ~/Library/Application\ Support/Google/Chrome/Default/History /tmp/h

  sqlite3 -separator $sep /tmp/h \
    "select substr(title, 1, $cols), url
     from urls order by last_visit_time desc" |
  awk -F $sep '{printf "%-'$cols's  \x1b[36m%s\n", $1, $2}' |
  fzf --ansi --multi | sed 's#.*\(https*://\)#\1#' | xargs open
