1, the Word document with MathType input formula, press and hold the "alt+\" key, you can convert the MathType formula into latex format. 2, the latex format formula code copied to word, before and after the "$" symbol, press "alt+\" key, the formula is switched to MathType format.For example: $-\sin \left (x \right) {{E}^{y}}+\frac{\cos \left (x \right)}{{{y}^{2}}}$, "alt+\", you can see the results. Therefore, the "alt+\" key in Word can be used to convert MathType and latex format formulas
