SYMPTOMS
When you attempt to insert into an equation of the Equation Editor or into a Word document through Symbol (on the Insert menu), the Left & Right Harpoon symbol or Right & Left Harpoon symbol (also called Double Harpoon), which are generally used to represent equilibrium, are not available.



CAUSE
In the case of the Equation Editor, the "Left & Right Harpoon" symbol or "Right & Left Harpoon" symbol are not included in its symbol set.

In the case of the Symbol dialog box, the font that contains these symbols, Math Ext (Mathext.ttf) is not installed on your computer, and because the Symbol dialog box can only insert characters from installed fonts, the symbols are not available.



WORKAROUND
To build an equation containing the equilibrium symbol, follow these steps:

 Install the Math Ext (Mathext.ttf) font. See the "More Information" section of this article for additional information. Build each side of the process in the equilibrium equation as a separate Equation Editor object. Insert the Left & Right Harpoon symbol or Right & Left Harpoon symbol between the two objects using the Symbol dialog box. To do so, follow these steps:  On the Insert menu, click Symbol. In the Font list, click Math Ext. Select the Left & Right Harpoon symbol or Right & Left Harpoon symbol.</li> Click Insert.</li></ol> </li></ol>

These symbols cannot be used directly in an Equation Editor object. They cannot even be pasted from the clipboard.

The Left & Right Harpoon and Right & Left Harpoon symbols (also collectively known as Double Harpoon) consist of two horizontal harpoon symbols (an arrow with only one barb or diagonal line on the point), one over the other one, pointing in opposite directions. The order of direction in the name is determined by which way the top harpoon points. These are the symbols most commonly used to represent equilibrium. The Double Harpoon is the symbol most predominantly required in printed text.

Following are alternatives that may be acceptable in some circumstances:


 * The Left & Right Arrow (consisting of a single horizontal line with an outward-pointing arrowhead at each end).
 * The Double Left & Right Arrows (consisting of a left arrow over a separate right arrow).
 * The Double Left & Right Arrow (consisting of two horizontal lines, one over the other like an equal sign, with an outward-pointing arrowhead at each end).

HTML documents have standardized on the "Less-Than Double-Hyphen Greater- Than" string (<-->).
