I have a student typing up her thesis. She needs to type external tensor, $\boxtimes$. Is there anyway to get that symbol in Microsoft Word? She doesn't know how to use TeX.
It does seem that Word will render the symbol by "copy and paste". It worked in implementation of Word (Office 10), and rendered as Cambria Math (font), with size $13$, which can be scaled to a different font size.
Edit: the symbol "$\boxtimes$" can be directly inserted from/within "Word" using:
Or, the better option if working within the Word "Equation Editor" environment:
The symbol in Word is referred to as "squared times."
It rendered as the exact image compared to "copied-and-pasted" symbol I inserted.
