System: Silver Macbook OS X Ver.: Leopard Backlit Keyboard?: No Sorry for the confusing title - Essentially my problem is that I'm unable to set new shortcuts for the F5 and F6 keys for my Silver Macbook. Since it doesn't have a backlit keyboard, there's no function for F5 and F6. I'd like to make them go to shortcuts such as "Show Desktop" and "Spaces", both of which are supported under the "Keyboard Shortcuts" Tab of "Keyboard & Mouse". So, I have them configured to match up to F5 and F6, but they do not activate the corresponding function when pressed. I have the "Use function keys as standard function keys" checkmark unset: I apologize for the fairly small problem...I just really want to free up those two keys! I appreciate any response. Thanks!
