Yes, it is possible to change the behavior of the dot key on the numeric keypad in Word to act as a decimal separator instead of a period. Here are the steps to do so:

1. Open Word and click on the "File" tab in the top left corner.
2. Click on "Options" at the bottom of the left-hand menu.
3. In the Word Options window, click on "Advanced" in the left-hand menu.
4. Scroll down to the "Editing options" section and check the box next to "Use the system separators".
5. Click on the "Decimal separator" drop-down menu and select the comma (,) option.
6. Click on "OK" to save the changes.

Now, when you type a number with a decimal point using the dot key on the numeric keypad, it will automatically be converted to a comma. This setting will apply to all documents you create or edit in Word on your computer.
