So in Word 2002 these settings (found on the web) are working for you but do not work in the website's word processor:
Auto Cap:
Click the "Word Options" button, located at the bottom of the menu. Select the "Proofing" option from the left panel of the Word Options window. Click the "AutoCorrect Options" button, near the top of the Proofing screen. Uncheck the box next to each type of automatic capitalization you want to disable.
Auto Text:
Create a new AutoText entry
1. In your Word document, select the text that you want to add to your gallery of AutoText entries.
2. On the Insert tab, in the Text group, click Quick Parts, point to AutoText, and then click Save Selection to AutoText Gallery.
3. Fill out the information in the Create New Building Block dialog box
If all is truly well with Auto Cap and AutoText then the remaining/continuing issue is the functionality of F6, F7, and F8 while in Word 2002.
As for the K330 keyboard it is programmable but strangely enough, not finding any definitive procedures per se.
I did come across this on a Logitech site:
-----------------
"To program or customize the F9-F12 keys on your Wireless Combo MK330, try to run the software as admin. Close the Logitech Setpoint Software by right clicking the icon from the system tray and select "Exit". Launch the software as admin, right click the Setepoint Software and select "Run as Admin". Customize the keys and see how it goes."
---------
Not the keys you need per se but could be a lead....
Do you have an icon for Setpoint or other icon for the keyboard on your task bar? Or if you go into Control Panel > Hardware and Sound > Devices and Printers > Keyboard and right-click (or click) there you may be able to access the keyboard controls or some similar configuration pages in that manner.
The objective is to find and verify the F6, F7, and F8 keys setting with respect to the functionality you need. Just focus on getting Pause to work if you can find the necessary options or choices. Then you will have a template for rewind and forward.
Unfortunately do not have a Logitech Keyboard available here to check or test.
