Chronicle allows multiple entries for a single subject or thread in the journal. This keeps related messages together and keeps replies with the original message so you can view the whole conversation as a unit rather than having to hunt the list for the whole discussion. There are three ways to "thread" journal entries together. First by simply replying to an email from the main Email tab. And second, when you locate a journal entry on the Journal screen you can either reply to it or just add a note to the thread by either a right-click > Add Entry to Highlighted Journal or clicking on the New Entry button in the upper right.
However, sometimes you can end up with multiple separate journals that are really on a single topic. If this happens, you can combine these separate journals into a single subject. To do this, check the box at the left of each journal you want to combine. Then right-click the journal list (or click the Edit button), and choose Combine Selected Journals.
At other times you can end up with multiple journal entries in the same thread that are about two different topics. You can remove an entry from an existing thread and make it its own subject in the journal list. To do this, select a journal with multiple entries, navigate to the entry you wish to remove, right-click the journal entry (or click the Edit button), and choose Split Highlighted Journal.
Correcting a previous entry
Chronicle uses date and time stamping to document what the conversation was. This is why after 24 hours you can not edit a journal entry. If a journal entry contains a mistake the only way to get the correct information into Chronicle is to add an a new journal note as part of the thread to make the correction: Right-click the journal and pick Add Entry to the Highlighted Journal, or click Edit and pick Add Entry to this Subject. When you add a journal this way, the new journal is linked to the original; the buttons next to Entry 1 of # for this subject move you through the associated entries. (These buttons are disabled if there’s only one journal for the subject.)
