"click" means to press the "enter/return" key?
"Click" means that you click the left mouse button in the field. This makes the field active, which must happen in order to convince the computer that something is being entered. When you leave the Old Password field blank (after clicking), the computer knows that the password is a blank space. Then, you can click in the New Password field and type the new password. "Enter", in this instance, does not mean that use the enter/return key.
