The `process_record()` function itself is deceptively simple, but hidden within is a gateway to overriding functionality at various levels of QMK. The chain of events is listed below, using cluecard whenever we need to look at the keyboard/keymap level functions. Depending on options set in `rules.mk` or elsewhere, only a subset of the functions below will be included in final firmware.

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