Keyboard layout toggle

[David Howard]

Hi to all.

Been using xfce3 for some time as my default wm, and have just moved up
to the beta2 of xfce4. It's a winner!

I use a number of non-latin keyboard layouts, and have set up panel
launchers using setxkbmap **. I have a panel button which reverts to
en_US, but I'd like to set up the button to toggle (by left click)
between kb layouts, as is possible with kxkb. Is there a way to define
this for a panel button? 

TIA, and congratulations on a brilliant desktop environment.
