 * `LAYOUTS`
  * A list of [layouts](feature_layouts.md) this keyboard supports.
-* `LINK_TIME_OPTIMIZATION_ENABLE`
+* `LTO_ENABLE`
  * Enables Link Time Optimization (LTO) when compiling the keyboard.  This makes the process take longer, but it can significantly reduce the compiled size (and since the firmware is small, the added time is not noticeable).
 However, this will automatically disable the legacy TMK Macros and Functions features, as these break when LTO is enabled.  It does this by automatically defining `NO_ACTION_MACRO` and `NO_ACTION_FUNCTION`.  (Note: This does not affect QMK [Macros](feature_macros.md) and [Layers](feature_layers.md).)
-* `LTO_ENABLE`
-  * Has the same meaning as `LINK_TIME_OPTIMIZATION_ENABLE`.  You can use `LTO_ENABLE` instead of `LINK_TIME_OPTIMIZATION_ENABLE`.

-* `LINK_TIME_OPTIMIZATION_ENABLE`
+* `LTO_ENABLE`
  * キーボードをコンパイルする時に、Link Time Optimization (LTO) を有効にします。これは処理に時間が掛かりますが、コンパイルされたサイズを大幅に減らします (そして、ファームウェアが小さいため、追加の時間は分からないくらいです)。
 ただし、LTO が有効な場合、古い TMK のマクロと関数の機能が壊れるため、自動的にこれらの機能を無効にします。これは `NO_ACTION_MACRO` と `NO_ACTION_FUNCTION` を自動的に定義することで行われます。(メモ: これは QMK の [マクロ](ja/feature_macros.md) と [レイヤー](ja/feature_layers.md) には影響を与えません。)
-* `LTO_ENABLE`
-  * LINK_TIME_OPTIMIZATION_ENABLE と同じ意味です。`LINK_TIME_OPTIMIZATION_ENABLE` の代わりに `LTO_ENABLE` を使うことができます。
