How do I get a white check box ?

In a text file of about 450 short lines (at most 25 characters).
I desire to use it as a means to verify a list of my DVDs.
I want to insert a rectangle box to put a check mark as I
check off each DVD. I desire the box to be just a empty white box outlined with
a thin black line.
Not matter what “Color” or pattern I pick, the box is SOLID BLACK, making it useless as a check box.
Can you help

Where are you getting the rectangle box? insert shapes? picture? form control check-box?
Some fonts include a character that looks like an empty box such as: □
To look for it, use the menu Insert->Special Character…

The answer would be different (and so is the ease of use, appearance, etc.) for each of the above.
