Mathtype can edit braces as follows:
Method 1: Edit with MathType template.
1. Open the MathType formula editor according to your own usage habits and enter the editing interface.
2. In the MathType toolbar of the editing interface, click the separator template. There are different separator templates such as left bracket, right brace and two braces, which you can choose according to your own needs.
Method 2: Input directly with the keyboard.
You also need to open MathType. In the editing area of MathType, you can directly enter braces with the keyboard in the English input state. However, one thing is that the parentheses entered in this way are very small, which can't be increased with the increase of formulas, and you can't switch to multi-line formulas to edit equations.
Method 3: Use shortcut keys.
When editing braces in MathType, you can also use shortcut keys to edit directly, without clicking the template in MathType toolbar. MathType brace symbols also have corresponding shortcut keys, and the left unilateral brace: Ctrl+T, Shift+[
Right unilateral brace: Ctrl+T, Shift+].
Tip: The braces edited by methods 1 and 3 can be automatically resized according to the formula content, while the braces edited by method 2 cannot be resized, so it is generally recommended to use methods 1 and 3. If you want to edit the equation, you can only use method 1 or method 3.
