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 to each other. ALSO: "ALT + Numpad number" in Word can quickly enter certain symbols that correspond to the ASCII code indicated by the number entered. But for the moment I have not found these symbols in relation to numbers. It should be understood that remembering the numbers corresponding to a few symbols helps to improve the efficiency of the input, and a lot of memory is not necessary for ordinary people.
