Greek Small Letter Mu Symbol

There is no legacy Windows Alt code for Greek Small Letter Mu because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+03BC, which you can use as μ in HTML, \03BC in CSS, or type with Alt+956 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Greek Small Letter Mu is outside both legacy code pages, which is why U+03BC is the identifier that works across Word, HTML, CSS, Python and JavaScript. HTML also defines the named entity μ for Greek Small Letter Mu, but the numeric form μ is safer when compatibility is uncertain.
