Definition of "globally" and related terms

The definition of "globally, global configuration" is not entirely correct for how it's used in our document.

It reads "a global setting is one that *applies to the entire user agent* or all content being rendered by it, rather than to a specific feature within the user agent or a specific document being viewed." However, the document also uses the term in reference to things beyond the scope of the user agent, such as "global settings on the device", "global volume level set through operating environment mechanisms", etc. We might want to generalize the definition to be global with respect to whatever's being discussed, whether it be the user agent, platform, or device.

Also, as a more minor point, the term "global configuration" is only used in the heading of this glossary entry, while the rest of the document uses the terms "global settings", its synonyms "global preference setting", "global option", and "global control", its subsets "global default setting", "global volume level",  and "global mute command". We might want to remove "global configuration" and settle on one term for "global settings".
