Long Left Right Double Arrow Symbol

There is no legacy Windows Alt code for Long Left Right Double Arrow because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+27FA, which you can use as ⟺ in HTML, \27FA in CSS, or type with Alt+10234 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Long Left Right Double Arrow is outside both legacy code pages, which is why U+27FA is the identifier that works across Word, HTML, CSS, Python and JavaScript. Long Left Right Double Arrow has no named HTML entity, so use the numeric escape ⟺ or the hex escape ⟺.
