o add your “Today’s Mood”, repeat the process and add “Today’s Mood” to the key and a description of your mood in the value text boxes and click Add Custom Field to save this information with the post.
On your next post, you can add a new book and mood to your meta-data. In the Custom Fields section, the Key will now feature a pull down list with the previously entered Custom Fields. Choose “Currently Reading” and then enter the new book you are reading in the value. Click Add Custom Field and then repeat the process to add “Today’s Mood”.
You only need to create a new “KEY” once, after which you can assign a value to that key for every post, if you so desire. You can also assign more than one Value to a key, for a post. This will come in handy for people who read more than one book at a time.
