+### Using fzf with tmux splits
+
+It isn't too hard to write your own fzf-tmux combo like the default
+CTRL-T key binding. (Or is it?)
+
+```sh
+# This is a helper function that splits the current pane to start the given
+# command ($1) and sends its output back to the original pane with any number of
+# optional keys (shift; $*).
+fzf_tmux_helper() {
+  [ -n "$TMUX_PANE" ] || return
+  local cmd=$1
+  shift
+  tmux split-window -p 40 \
+    "bash -c \"\$(tmux send-keys -t $TMUX_PANE \"\$(source ~/.fzf.bash; $cmd)\" $*)\""
+}
+
+# This is the function we are going to run in the split pane.
+# - "find" to list the directories
+# - "sed" will escape spaces in the paths.
+# - "paste" will join the selected paths into a single line
+fzf_tmux_dir() {
+  fzf_tmux_helper \
+    'find * -path "*/\.*" -prune -o -type d -print 2> /dev/null |
+     fzf --multi |
+     sed "s/ /\\\\ /g" |
+     paste -sd" " -' Space
+}
+
+# Bind CTRL-X-CTRL-D to fzf_tmux_dir
+bind '"\C-x\C-d": "$(fzf_tmux_dir)\e\C-e"'
+```
