Placing an "x" over an existing box

If it is a "checkbox" you can double-click it and set it to "Checked" or "Not checked"

If it is a "Character" you need to insert a new one.

In the Insert>Symbol>All Symbols menu, the "Ballot Box with X" and "Ballot box with check" are in the eighth segment down.  Double-click it to insert it as a character replacing the one you have.

Hope this helps

Not contradicting John whatsoever, but if this is a properly constructed form (such as would be downloaded from a web site) you should not have to edit/replace the characters in the document. You should be able to either click the box to place a check in it or tab to the check box & press the space bar.

I have a feeling that there may be something more about this application document & its source that you haven't revealed :-) Are you sure this application is intended to be completed electronically?

Okay, sorry it took me so long. I have placed the file on Google Docs. In all fairness, Google Docs distorted the file, and I put it back as well as I could, but lets not lose focus. The issue was placing a "x" or check mark over a square where it asks for gender (Pg. 1). Please let me know how it goes. I have made the file public, so everyone can access it.

First, thank you all for your feedback. I am very new to formatting MS Words objects, and I am appreciative. This is what I ended up doing. The application I am filling out belongs to MSW program at CSU Hayward, and you can check out the format for yourself if you like. The question I am trying to answer by typing (not printing, filling and faxing) was "Your gender". Common question for most college apps!

I double clicked on the box, a symbol window appeared, full of different small symbols. I used the "checked" symbol for simplicity purpose. It did take away the box in front of the "Male" word, which was not my intention, but I am okay with it, and replaced it with a checked mark.

I really wanted to place a check in the box ( I think it would be placing one object (a box) under a another (a check mark), and making the box transparent. I did try to place a box and make it transparent, but I can't make the box to match the "Female" box next to it. Due t whatever reason, the box dimensions are only somewhat controllable.

As for the programer and not making the job easier for the person filling out the form, well.... I let you go in there and decide for yourself how a university application may look like for a Master's degree!

Thank you again for all your feedback and help.

I concur with your second paragraph, which I think is what John's 'If it is a "character"' option is intended to deal with. 

Print, fill in manually and scan/email or fax is also an option in that case, but then you have to be able to do all those things.

If it is a Word Document built on either Windows or Mac Word with "legacy forms", it would be strange for the developer not to have protected for forms because it's not hard to do. But I suppose that could happen, and that the user would need to be able to enable the Developer tab via Word->Preferences then protect the form.

It would I think be even stranger for a developer to use content control checkboxes because they are only understood by Windows Word 2010 and 2013 (not even the Word Web App, as far as I can tell). In Mac Word you would have to use John's 'If it is a "character"' option. Even that will not work if the controls have been marked as not deletable.

Using old ActiveX controls also wouldn't work on Mac Word, but should respond to the 'If it is a "character"' option as long as the Document has not been protected for forms. You'd be deleting a graphic rather than a character in that case.

What happens to Acrobat Forms if you open them in Word these days?
