By default the NKRO max usage is set so as to maximize compatibility, however certain less frequently used keys (F13-F24 and INTL1-8) will not work with it. One solution is to set `CONFIG_ZMK_HID_KEYBOARD_NKRO_EXTENDED_REPORT=y`, however this is known to break compatibility with Android and thus not enabled by default.

If `CONFIG_ZMK_HID_REPORT_TYPE_HKRO` is enabled, it may be configured with the following options:
| Config | Type | Description | Default |

| `CONFIG_ZMK_HID_KEYBOARD_REPORT_SIZE` | int | Number of keyboard keys simultaneously reportable | 6 |
If `CONFIG_ZMK_HID_REPORT_TYPE_NKRO` is enabled, it may be configured with the following options:
| Config | Type | Description | Default |

| `CONFIG_ZMK_HID_KEYBOARD_NKRO_EXTENDED_REPORT` | bool | Enable less frequently used key usages, at the cost of compatibility | n |
