Based on info from but with modified behavior and fixed to work with iTerm2 version 3 or later. It will not work with older versions of iTerm. The modified behavior is to open a new terminal window for each invocation instead of reusing an already open window. Update - The original author released a build script for the newer iTerm2 versions at that keeps the original behavior of reusing an open iTerm2 window.

To open iTerm2 at selected folder with keyboard shortcut

  1. Run Automator, select a new Service
  2. Select Utilities -> Double click ‘Run AppleScript’
  3. Service receives selected 'folders' in ''
  4. Paste script:
# i3-get-window-criteria - Get criteria for use with i3 config commands
# To use, run this script, then click on a window.
# Output is in the format: [<name>=<value> <name>=<value> ...]
# Known problem: when WM_NAME is used as fallback for the 'title="<string>"' criterion,
# quotes in "<string>" are not escaped properly. This is a problem with the output of `xprop`,
# reported upstream:

# OpenVPN is fairly simple since it works on OpenSSL. The OpenVPN server contains
# a root certificate authority that can sign sub-certificates. The certificates
# have very little or no information on who they belong to besides a filename
# and any required information. Everything else is omitted or blank.
# The client certificate and private key are inserted into the .ovpn file
# which contains some settins as well and the entire thing is then ready for
