-Notice how all of these arguments match up with the first half of the `KEYMAP()` macro from the last section? This is how we take a keycode and map it to our Matrix Scan from earlier.

 ##### State Change Detection
 
-The matrix scanning described above tells us the state of the matrix at a given moment, but your computer only wants to know about changes, it doesn't care about the current state. QMK stores the results from the last matrix scan and compares the results from this matrix to determine when a key has been pressed or released.

 Let's look at an example. We'll hop into the middle of a keyboard scanning loop to find that our previous scan looks like this:

 At any step during this chain of events a function (such as `process_record_kb()`) can `return false` to halt all further processing.
