I'm trying to play Minecraft (A video game) that makes use of F3. However, I'm on a laptop which requires you to hold down Fn in order for a F# key to be registered. The problem is that Ubuntu registers Fn+F3 as the lock keyboard shortcut. How can I turn this behavior off? Also, the shortcut isn't appearing in Keyboard.

Here is some background info that could help.
Check out the section on replacing shortcut keys. It's near the bottom. You can use xbindkeys to set hot-keys. Here's how:
Install xbindkeys with:
sudo apt-get install xbindkeys.
Create a default config file with:
xbindkeys --defaults > /home/your-user-name/.xbindkeysrc
Install the GUI for xbindkeys with:
sudo apt-get install xbindkeys-config
The xvkbd utility must also be installed:
sudo apt-get install xvkbd
Next, bring up "Run Application" and type
xbindkeys and xbindkeys-config
If you want to override the system hot-keys already in effect, you need to install xmacro:
sudo apt-get install xmacro
Start xmacro with xmacroec :0.0
After giving a key that will allow you to quit xmacro, you can press the key(s) you want to know the code for. You can then use xbindkeys to override the system hot-keys that are bothering you.
Here is the home page for xbindkeys.
