-NOTE: **Note:** If you let the system create your URL Title for you it will convert spaces into underscores by default. For example, if the title of your entry is "Joe's First Entry" it will be converted to "joes_first_entry". If you prefer dashes to be used instead of underscores you can change it with the **Word Separator for URL Titles** preference under `Admin --> Channel Administration --> Global Channel Preferences`.

 ### Entry Fields
 
 The names and types of entry custom fields displayed will be determined by what [Fields](/fieldtypes/overview.md) you have defined for this channel.
 
-If an entry field is set to be "hidden" by default, it will have to be expanded by clicking on the field name before content can be entered.
+If an entry field is set to "Hide field?" in the field settings, it will display as collapsed by default and will have to be expanded by clicking on the field name before content can be entered. This is overridden by the custom Publish Layout setting for that field.
 
-The fields can be [conditionally hidden](control-panel/field-manager/conditional-fields.md).
+If an entry field is set to "Collapse" in a Publish Layout, it will initially display collapsed and will have to be expanded by clicking on the field name before content can be entered.
+
+If an entry field is set to "Hide" in a Publish Layout, it will not display at all, though its content will be preserved and unchanged if someone edits the entry. If the field is set to required, it cannot be hidden via a Publish Layout setting.
+
+Fields can be [conditionally hidden](control-panel/field-manager/conditional-fields.md).
 
 In order for the field to be available when publishing or editing an entry, it needs to be assigned to the channel the entry is in.
 
 This can be done in two ways:
 - assign custom field to a [Field Group](/control-panel/field-manager/field-manager-settings.md#createedit-field-group) which is associated to the Channel
 - assign field directly to channel by editing [Channel preferences](control-panel/channels.md#fields-tab)
 
-When working with [templates](templates/overview.md) you will be referencing the field by its short name or tag pair. For convenience the short name can be displayed next to the field's name in the publish form (<img style="margin-bottom: 0px; vertical-align: middle; display:inline-block;" src="../_images/field_short_name.png" alt="field short name">) and the variable(s) required to display the content will be copied to the clipboard when clicked. Displaying the short name can be toggled on or off in the [Role](control-panel/member-manager.md) settings.
+TIP: **Tip:** When working with [templates](templates/overview.md) you will be referencing the field by its short name or tag pair. For convenience, the Publish form has a handy way to display the field short name in a click-to-copy format: (<img style="margin-bottom: 0px; vertical-align: middle; display:inline-block;" src="../_images/field_short_name.png" alt="field short name">). This is enabled at the role level and controlled with the ["Show field names on Publish" setting](control-panel/member-manager.md#role-tab).
 
 NOTE:
 Due to security restrictions in modern browsers quick copying code via the shortname is only supported when on HTTPS.
