Don't have cairo but maybe something along these lines
Code:
sudo apt-get install xdotool
Then create a .desktop either in this location or as appropriate to cairo
Code:
gedit ~/.local/share/applications/dash.desktop
Use whatever you wish for Name= & Icon=, sometimes just the icon name is ok, otherwise full path, the icon below isn't really suitable though may be ok
Code:
[Desktop Entry]
Version=1.0
Type=Application
Name=Dash
Icon=/usr/share/unity/5/launcher_bfb.png
Exec=xdotool key super
Then add dash.desktop to your cairo dock, if need be make dash.desktop executable -
chmod u+x ~/.local/share/applications/dash.desktop
or right click on > properties > permissions
