Sometimes it is useful to record a comment about a specific customization. Use the Add Comment item from the [State] menu to create a field for entering the comment. The comment you enter will be saved, and displayed again if you again view the same option in a customization buffer, even in another session.
The state of a group indicates whether anything in that group has been edited, set or saved. You can select Set for Current Session, Save for Future Sessions and the various kinds of Reset operation for the group; these operations on the group apply to all options in the group and its subgroups.
Near the top of the customization buffer there are two lines containing several active fields:
[Set for Current Session] [Save for Future Sessions] [Reset] [Reset to Saved] [Erase Customization] [Finish]
Invoking [Finish] either buries or kills this customization buffer according to the setting of the option custom-buffer-done-function; the default is to bury the buffer. Each of the other fields performs an operation--set, save or reset--on each of the items in the buffer that could meaningfully be set, saved or reset.
