## Magic keycodes
There are two `__attribute__ ((weak))` placeholder functions available to customize magic keycodes. If you are not using that feature to swap keycodes, such as backslash with backspace, add the following to your `keymap.c` or user space code:
```c
uint16_t keycode_config(uint16_t keycode) {
return keycode;
}
```
Likewise, if you are not using magic keycodes to swap modifiers, such as Control with GUI, add the following to your `keymap.c` or user space code:
```c
uint8_t mod_config(uint8_t mod) {
return mod;
}
```
Both of them will overwrite the placeholder functions with a simple return statement to reduce firmware size.
