When typesetting, first add the size, you can add the maximum size and minimum size, then click the display layer in the lower left corner to set the push code, then click the number just added (previously gray) to activate it, and then click the push code to set the display settings. If it is an insertion code, hold down shift and click the button on the left to display the settings, and continue until it becomes an insertion and deletion number. Click the code you want to insert, and then click it.
