Preferences, Scopes etc. [message #300305]

I'm always afraid to post a question here as many times I find it's dumb question as I'd failed to do my research first. But I think I've done all I can on this one.

1) When using ScopedPreferenceStore / PreferenceStore how can I enumerate the names of the values stored in a store or context?

2) How do I delete an item? I can setValue and getValue but there's no remove.

3) PreferenceStore seems implemented for ConfigurationScope, DefaultScope, InstanceScope and ProjectScope. But, there's nothing for the file level except for the PersistentProperty methods. Am I missing something? Is there a FileScope?

For #2: I would think that by (re)setting the items value to the
default, it would effectively be removed from any persisted preferences.
Did you try that out?

No, I didn't try resetting to the default value. I'll try that. It's not intuitively obvious from the documentation.

How would you remove something from the default store?
