For those not initiated into the computers world or those who are starting to learn how to use a computer, the basics are to learn how to write a text in document .
In you want for example to write a text and suddenly you realize you had to write all text with uppercase letter not lowercase it is a simple command to transform all text .
In this case with a simple key combination you can change the text in capital letters (caps) in lowercase and vice versa (eg if you receive a text from anyone and you want to turn upper and lowercase).
With a simple text selection in Microsoft Word press “Ctrl + SHFT + A” and the letters will transform into small or large !
