Annotation in box

Greetings!

I've inherited a drwaing that has numbers in boxes.  Selecting the box in question opens the Note manager, but Border type is 'None'.  If I right-click on it, option "Edit Text in Window" is available w/ the following string:

, (4 being the number w/in the box that was clicked).

I'd like to know how to place this same type of boxed note in this drawing.

Thanks in advance,

Roger
