Let's talk casually.

The methods of making subscripts in word are: for example, making H2O.

1。 Enter H2O first, then brush 2 black-CTRL+D or dot font (O)-and there is a "subscript" function at the lower left of the font tab, just check it-and finally confirm. (There is a superscript here, too. You should be able to see it, right? )

2。 Enter H2O first, then brush 2 black -CTRL+= (but be sure to turn off conflicting software such as QQ). This method is relatively simple. {Drag a tool to the toolbar, and any tool will work. }

CTRL+SHIFT+= is a subscript.

3。 Just click Tools (T)- Customize-Command Tab-Select Format in Category-Click the scroll bar in the command to find "Subscript", and hold down the button pointing to X2 to the appropriate position on the format toolbar until a black "I" symbol appears on the toolbar. Just release the left button, brush "2" in black next time, and click the X2 button. This method is complicated for the first time, but it will be simple later.
