I don't think the "Method 1" on that page is all that tedious. It's
basically two steps, one on the old computer and one on the new computer.
Download the zip file and unzip it into your Templates folder. Double-click
the AutoCorrect.dot template. When the template opens in Word, click the
Export button. When the macro finishes, save the resulting document.
Take the document and the AutoCorrect.dot template to the other computer.
Double-click the template. When it opens in Word, click the Import button,
and select the document.
Unless you can't use Method 1 for some reason, you can completely ignore
Method 2. Now, that one *is* tedious -- but that's why Method 1 was created.
And the answer to your last question is no -- the AutoCorrect entries aren't
(necessarily) all in one place. The macro in the AutoCorrect template
collects them into one document, which is why you should use it.
