+#### New window/pane using cwd

+`nnn` does not change the process cwd while navigating. This may produce unexpected behaviour when using functions such as:
+
+`tmux new-window -c "#{pane_current_path}"`
+
+*See [author comment](https://github.com/jarun/nnn/issues/332#issuecomment-533937941) and issue #565 for more details.*
+
+One possible workaround is to extract the path from the cwd command that nnn uses:
+
+`lsof -c nnn | grep cwd`
+
+To get the path on the last executed cwd command:
+
+`lsof -w -c nnn | grep cwd | tail -n 1 | awk '{print $9}'`
+
+A script example`tmux_split_curdir.sh`:
+
+```bash
+#!/bin/bash
+cwd=
+cc=$(tmux display -p '#{pane_current_command}')
+if [ $cc == "nnn" ] ; then
+   cwd=$(lsof -w -c nnn | grep cwd | tail -n 1 | awk '{print $9}')
+else
+   cwd=$(tmux display -p '#{pane_current_path}')
+fi
+
+tmux split-window -c "$cwd"
+```
+
+Adding this script to your tmux path allows it to be run with `run-shell`:
+
+`bind -n KEYS run-shell "tmux_split_curdir.sh"`
