This is where we get to have a little fun! Well, maybe not quite "drink-a-twelve-pack-of-root-beer-and-reinstall-Linux" fun, but at least it will allow you to get creative using the medium of expressive scancode remapping.
You'll find the example keymaps at the bottom of the sketch:

KEYMAPS_FINISHED
Basically, these are a bunch of macros that implement the steps
necessary to create mapping arrays for the converter's scancodes to the
values expected by the host device. The PS2_CODESET3_KEYMAP macro maps
the default PS2 scan codes into an order that allows us to define our
key layers laid out like the actual keyboard. Don't get confused by the
layout however... that is what the 122-key Model M looks like.
The keymaps above however work well on my 101-key Model M, and all of the scan codes are in the same spot on both keyboards except for three: Print Screen (F23), Scroll Lock (F24), and Pause (at the center of the arrow keys on the 122). If you're interested you can find complete diagrams of the scancodes here: http://www.seasip.info/VintagePC/ibm_1390876.html.
Here I've defined 2 layers; the first is the pretty standard layout for a Model M, except that I got rid of the Caps Lock key (which I consider to be useless) and moved the Left Control key up in its place (where it belongs). The Left Control key then becomes a function key (FN1) that switches the keyboard to Layer 2.
The second key layer is mostly transparent ("TRNS") which means that whatever is on the layer below is used for that key. You'll find the layer 2 keys near Insert and Delete, as well as on the number pad. Insert becomes a function key that when held down for 5 seconds resets the pairing of the Bluefruit, and Delete sends the Bluefruit a reset signal. On the number pad are "mouse key" controls - if you hold down FN1 and use those keys, you can move the mouse cursor and use BTN1 and BTN2 to left and right click, just like you would with any other pointing device.
Have fun and play around with this part until you have things set up the way you like them... you can find more documentation on how to do key mapping in TMK's documentation:
