# This script opens a gnome-terminal in all selected directories, if nothing is selected it opens in current directory.
#
# You need to have caja-actions installed to use scripts.
# Put this file in your ~/.config/caja/scripts/ directory. Then:
# chmod +x ~/.config/caja/scripts/open-terminal-here
# vim ~/.config/caja/accels
# add the following line
# (gtk_accel_path "<Actions>/ScriptsGroup/script_file:\\s\\s\\shome\\sUSER\\s.config\\scaja\\sscripts\\sopen-terminal-here" "F4")
# where USER is your user name. This binds the script to F4, but of course you can change the shortcut as you like.
# Quit Caja (caja -q) and restart it.
# I've tested it on Ubuntu 19.10.
