UCx provides a very useful feature on Nortel IP phones that is not mentioned in the documentation - a list of all available features.
To display the list, simply press the Services button on your IP phone (the button with the globe). You can then scroll through the feature list using navigation keys and once you locate a feature you are looking for, press the Invoke softkey. In other words, if you use a Nortel IP phone and the Feature key is disabled (or if you occassionally forget a BCM/Norstar feature code), the Services button is your best friend.
