Functional differences between two fine-tuning font keys in Word

Many friends know that the "CTRL +]" and "ctrl+[" key combinations in Word increase or decrease the font size by one point. This is convenient, but there is no way to change the font size by 0.5 points. What if we want to quickly increase or decrease the font size by the order of the font size listed in the Font Size box in Word software , eh?

In fact, we can fine-tune the font size, with the "ctrl+shift+>" or "ctrl+shift+<" key combinations, they can in the Word document in the Font Size box listed in the order to increase or decrease the font size. For example, assuming the font size of the currently selected text is 10 points, the font size of the selected text changes to 10.5 points when the "ctrl+shift+>" key is pressed.
