YAY! Here's how to do it...

With your WORD program open, click on the "Insert" button on the toolbar.

In the drop-down window, click on "AutoText"

In the new drop-down window that opens, click again on "AutoText". An "Auto Correct" window opens ups.

Click on the "AutoText" tab.

At the top of the sheet that comes to the front, remove the check in the box before "Show AutoComplet suggestions"
