Ah I see. Is it only in Word? Or is it in all that it isn't working?
You may want to try the following, in order, to see if it will get it working...
1. Uninstall the keyboard driver.
2. Uninstall synaptics touchpad driver and application.
3. Reboot, allowing the computer to reinstall the drivers. If it doesn't reinstall any of the drivers on its own after the reboot, then you would need to install them yourself. However, it is best to try the reboot first.
4. Now open up a few different programs to test it in.
