Since Microsoft Word isn't a TRL-specific product, I won't be writing directions on how to use it. What I will do is link you to some videos which I've found helpful on how to get the most out of Word.
Microsoft Word is found in all of our internet computers and is the most popular word processing program available. I found this free series on YouTube covering everything there is to know about Word. I'll link a few of the most relevant ones on this page, but you can check out the rest here if you need extra information.
P.S.: Bear with this guy, because as knowledgeable as he is, he tends to be long-winded.
