G4-cube console switching problem

[Rich Johnson <rjohnson@dogstar-interactive.com>]

How do I switch text-consoles with an Apple Pro Keyboard.  Neither  
cmd-ctl-F(n) nor opt-ctl-F(n) do anything.
I can switch _from_ the gdm using cmd-ctl-F(n)...but I can't get  
back!  What am I missing?

The system is a G4 running testing--and soon to run MOL.

Please don't tell me I need to use the left ctl-opt--those two keys  
are dead from an old "coffee hazard" :-(

Thx--
