As mentioned above, the Add New Key option allows you to add a new key/value pair to a lexicon file. If a particular key is not included in a lexicon file, you can use this option to add the key. For example, if you want to globally replace the “Elapsed Active Time” and “Elapsed Active Time Numeric” property descriptors with “Runtime” and “Runtime Numeric”, you must add those keys to the lexicon file. This is sourced in the control module. So, you must add the new keys in the control module.
