This template renders a Key top as found on typewriters and computer keyboards including a standardized or common symbol if available, e.g. from ISO/IEC 9995-7. Keys for which there is an associated Wikipedia article are rendered with a hyperlink. Unlike {{Key press}}, this template is not intended to be used for combinations of multiple keys, i.e. “keyboard shortcuts”. It shall be used in descriptions of the physical keys and their functions.
The first, mandatory parameter holds the “natural” key name which is used to select a symbol and link. Its contents is usually also output unchanged next to the symbol unless the second parameter is set to an explicit label, which most often will be blank to suppress the label. The third, also optional parameter, is a binary switch that toggles alternate representations of a very limited selection of symbols: ⌃ vs. ⎈ , ↩ vs. ↵ vs. ⏎ , ⌤ vs. ⎀, ■ vs. ◼ and ● vs. 🔴.
To indicate text is a variable name. Use for any variable names except those including "I" (uppercase i) and/or "l" (lowercase L); for these, {{Varserif}} should be used to ensure a noticeable distinction
To display parameters as used in code (i.e. with triple braces), especially to indicate relationships between them. May be combined with {{Para}} above
To indicate text is source code. To nest other templates within {{Code}}, use <Code>...</Code>. {{Codett}} differs only in styling: someMethod becomes someMethod
(or {{Deprecated code}} ) To indicate deprecated source code in template documentation, articles on HTML specs, etc. The {{Dc2}} variant uses strike-through (<blink>) while {{Dcr}} uses red (<blink>).
