Remove shortcuts from titlebar

[dehawkinz]

I accidentally dragged a couple of programs to my title bar, and can not work out how to get rid of them - I did not want them there, but there is no 'delete' option when I right click on them.

I am using the un-enhanced gnome desktop under Mint12 - the one with Applications and Places at top left
System:
Kernel: 3.0.0-12-generic i686 (32 bit gcc 4.6.1)
Desktop: Gnome (Gtk 2.24.6)
Distro: Linux Mint 12 Lisa

I am sure there is an 'obvious' way to do it, but I am not seeing it

You have to hold ALT whilst you click/drag.
