};

v7

• L1, L2 を入れ替え
• mod tap を削減

v8

• JP_* を使用し、 L2 を削除

v9

• L2, L3 を入れ替え
• L3 から戻れないのを修正

---

OSL の挙動・制約について調べておく必要がある。確かに Graphical Configurator でも制約があった。

v10

• 記号の配置を ascii table に近い形に変更
• keymap の整形

#define IGNORE_MOD_TAP_INTERRUPT はメモ。 config に足す。

v11

• SFT -> OSL3
• GUI/SP -> SFT/SP
• Alt -> GUI
• Ln -> TOn/OSLn
• move reset key
• add 1 phisical key

v12

• remove 1 phisical key
• add L4 and L5 (mod key layer)

v13

• sort mod key
