right clikc -> actions -> ... here

you might want desktop files that have

X-Enlightenment-Action-Mime=inode/directory

in them - then they will be included in that menu and whatever is
executed is passed the dir when run as an argument. example:

[Desktop Entry]
Type=Application
Name=Dir xmessage
Exec=xmessage
Icon=video_player
NoDisplay=true
X-Enlightenment-Action-Mime=inode/directory
