F10 and F11 don't work for button emulation

[chris moss]

I have just reinstalled YDL 2.2 on an iBook dual USB. I had forgotten the 
CD-R/W fix needed for this to be able to install yaboot and configure it. I 
booted from Tasty Morsels and fixed that, but in my haste over the failing 
install, I must have omitted to check the settings for 3-button mouse 
emulation. I can use a USB 3-button mouse, but being an iBook I don't always 
want to use a mouse. Can I somehow set F10 and F11 for this now the 
installation is done?
