To insert an equilibrium symbol in MS Word, users can utilize the Equation Editor if it is installed. This can be accessed through the Insert menu by selecting Object and then Microsoft Equation. If the Equation Editor is not available, it may require installation from the original disk. Alternatively, a double-headed arrow can be used as a temporary substitute, pending approval from the instructor. For those with the MS Mincho font, the symbol can be found by selecting Insert, then Symbol, and choosing MS Mincho from the font menu. This font contains a variety of symbols that may include the desired equilibrium symbol.
