==== {{flag|英國}}擴展鍵盤佈局 ====
英國擴展鍵盤映射適用於Microsoft Windows、Linux、ChromeOS，通過使用AltGr或[[死鍵]]與其他鍵組合，允許許多帶有[[變音符號]]的字符<!--（包括在歐洲諸國使用的字符）-->。<!--The [[QWERTY#United Kingdom (Extended) Layout|UK-Extended keyboard mapping]] (available with Microsoft Windows, Linux and ChromeOS) allows many characters with [[diacritical mark]]s (including those used in other European countries) to be generated by using the AltGr key or [[dead key]]s in combination with others.-->

注：此處用虛線圓（◌）表示死鍵。{{keypress|`}}[[重音符]]鍵是唯一一個充當獨立死鍵的鍵，因此不會像鍵帽上顯示的那樣響應。所有其他的都由AltGr調用。另外，{{keypress|AltGr|shift|0}} (°) 是[[度數符號]]；{{keypress|AltGr|shift|M}}º是陽性[[序數指示符]]。<!-- ''有關使用死鍵可用字符的完整列表，請參閱 [[QWERTY#Chrome OS|QWERTY#ChromeOS]]。''--><!--Notes: Dotted circle (◌) is used here to indicate a dead key. The {{keypress|`}} ([[grave accent]]) key is the only one that acts as a free-standing dead key and thus does not respond as shown on the key-cap. All others are invoked by AltGr. <br>
{{keypress|AltGr|shift|0}} (°) is a [[degree sign]];  {{keypress|AltGr|shift|M}} (º) is a masculine [[ordinal indicator]]. ''For a complete list of the characters available using dead keys, see [[QWERTY#Chrome OS|QWERTY#ChromeOS]].''-->
