Change Case in MS Word

Hi readers! Just a brief one.
Have you ever wonder how to change from lower case to upper case or vice versa in MS Office Word? It is really simple. Highlight the targeted word/phrase and then press Shift+F3 keys on your keyboard simultaneously and examine the output. Here are few examples:
First, highlight the text.

Then press Shift+F3. You will see that only the very first letter is changed to uppercase (or capitalised).

When you press the combination keys one more time, all of the selected text will be capitalised.

Try to repeat the process and see what will you get.
Until next time, happy trying~
