How do I fill in checkboxes without using Restrict Permissions?

[VicVicVic]

Hello. This seems like a simple thing to do, but I cannot figure out a way to do it. After trying on and off for over a year via search engine searches and self testing, this is my first time asking.

In a Word document with checkboxes, I know that I can Restrict Permissions under the Review tab in order to fill in checkboxes with one click. However, there are times I do not want to Restrict Permission. If I don't Restrict Permissions, clicking on a checkbox once does not do anything. If I click it twice, a pop-up of Check Box Form Field Options appears, and I can change the Default Value to "Checked." This seems like a lot of unnecessary clicks and time spent. Is there a way to quickly fill in checkboxes without Restrict Permissions? (I initially was hoping that by holding down a key and clicking, the checkboxes could be filled.)

Thank you.
