I'm creating a technical document using Microsoft Word 2010 in Windows 7. I have various pieces of long technical terminology that I regularly use, and typing this jargon manually hundreds of times would significantly increase the time I spend writing the document.
I was looking for a way to add custom autocompletion entries in Word so that whenever I typed a trigger word or abbreviation for a given technical term, Word expanded the text to the full term. I worked out how to do this, and decided it'd be worth writing up the answer to SU because of how relatively hidden away it is - for me, at least.
This is useful for any pieces of text that often need to be repeated in a document, such as the name of a company or brand in legal documentation, a historical figure in an essay, or a company or email address in professional correspondence.
How can I have Word automatically expand to a word or phrase whenever I type a trigger word or abbreviation for it?
