Assign a key for Changing Keyboards layouts

[nemonein]

Hi!

I'm using Ubuntu 8.10 64 bit.
I want change the keyboards layouts between US Dvorak and US Qwerty.

In Keyboards Layouts Options(System-Preferences-Keyboard-Layouts-Other Options),
I can assign a key for changing the layouts. (In Layout Switching Menu)
However, the allocable keys are restricted, such as ctrl, alt, shift, or Caps-Lock.

I would like to assign a different key (not listed on above options) for changing, like Menu, or one of the functions keys(eg F11, F12..).
Is is possible?

Thanks in advance!
