In Microsoft Office, you can use the Insert - Symbol command. If you don't see how to select Insert and then Symbol, you can often do [Alt-I] [Alt-S], which is how they did it in Word 2003. This definitely works in any recent flavor of Word, so you can go to Word and create it there.
After you do Insert - Symbol, you may be given a brief list. If so, select More (unless theta is there from the previous time).
You can select from thousands of symbols. You often need to browse them all to learn where the symbol you want is. However, there is a pulldown menu for categories (not reliable). If you select Greek... from the list, you will find theta. Both upper- and lowercase are available.
To insert into any other program, including Microsoft products that you can't do Insert - Symbol, create the symbol in Word, highlight it, then do Copy, followed by a Paste into the application you want. Complicated, but it works. Once it's in your application you can late Copy and Paste within that program.
The theta character is a O with a horizontal bar across the middle. As to the keyboard, it depends on what operating system you are using. (It is too difficult to show on Answers.com due to formatting restrictions.) But, have a look in special characters, or something similar, in whatever word-processing program you are using.
