## Split Keyboards
When handedness is predetermined via an option like `SPLIT_HAND_PIN`, you might need to configure a different key between halves. To do so, add these entries to your `config.h` file:
When [handedness](feature_split_keyboard.md#setting-handedness) is predetermined via options like `SPLIT_HAND_PIN` or `EE_HANDS`, you might need to configure a different key between halves. To identify the correct key for the right half, examine the split key matrix defined in the `<keyboard>.h` file, e.g.:
```c
#define LAYOUT_split_3x5_2( \
L01, L02, L03, L04, L05, R01, R02, R03, R04, R05, \
L06, L07, L08, L09, L10, R06, R07, R08, R09, R10, \
L11, L12, L13, L14, L15, R11, R12, R13, R14, R15, \
L16, L17, R16, R17 \
) \
{ \
{ L01, L02, L03, L04, L05 }, \
{ L06, L07, L08, L09, L10 }, \
{ L11, L12, L13, L14, L15 }, \
{ L16, L17, KC_NO, KC_NO, KC_NO }, \
{ R01, R02, R03, R04, R05 }, \
{ R06, R07, R08, R09, R10 }, \
{ R11, R12, R13, R14, R15 }, \
{ R16, R17, KC_NO, KC_NO, KC_NO } \
}
```
If you pick the top right key for the right half, it is `R05` on the top layout. Within the key matrix below, `R05` is located on row 4 columnn 4. To use that key as the right half's Bootmagic Lite trigger, add these entries to your `config.h` file:
```c
#define BOOTMAGIC_LITE_ROW_RIGHT 4
#define BOOTMAGIC_LITE_COLUMN_RIGHT 1
#define BOOTMAGIC_LITE_COLUMN_RIGHT 4
```
By default, these values are not set.
