機械鍵盤 NKRO 是什麼？為什麼你需要全鍵無衝突？
在挑選機械鍵盤時，常看到包裝上寫著「NKRO (N-Key Rollover)」。這到底是什麼意思？對於不打遊戲的人重要嗎？
鬼鍵 (Ghosting) 與 鍵位衝突 (Jamming)
在傳統的薄膜鍵盤設計中，按鍵線路是共用的。當您同時按下多個按鍵 (例如玩遊戲同時按 W + Shift + 空白鍵 + R)，鍵盤可能會：
- 衝突 (Jamming)： 第四個按鍵訊號發不出去，角色沒反應。
- 鬼鍵 (Ghosting)： 觸發了一個您根本沒按的鍵。
NKRO 的意義
NKRO 代表「N鍵無衝突」，意即無論您同時按下多少顆按鍵，電腦都能精準接收到每一顆訊號。這對於音樂遊戲 (如 DJMAX) 或快節奏的 FPS/MOBA 遊戲至關重要。
6KRO vs NKRO
許多 USB 鍵盤預設為 6KRO (同時最多 6 鍵)，這是受限於舊式 USB 協議。現代電競鍵盤通常能透過驅動或是內部處理突破限制達到全鍵無衝。

What is NKRO on Mechanical Keyboards?
When buying mechanical keyboards, you often see "NKRO (N-Key Rollover)" on the box. What does it mean? Does it matter for non-gamers?
Ghosting vs. Jamming
In traditional membrane keyboards, circuits are shared. When you press multiple keys simultaneously (e.g., W + Shift + Space + R), the keyboard might fail:
- Jamming: The 4th key signal isn't sent. Your character doesn't react.
- Ghosting: A key you didn't press is registered erroneously.
The Meaning of NKRO
NKRO stands for "N-Key Rollover," meaning no matter how many keys you press at once, the PC registers every single one accurately. This is critical for rhythm games (like DJMAX) or fast-paced FPS/MOBA games.
6KRO vs. NKRO
Many USB keyboards default to 6KRO (max 6 keys) due to legacy USB protocols. Modern gaming keyboards use drivers or internal processing to bypass this limit.
