These are two components to the Marquee system. There is no limit to the number of Marquees and Marquee Styles you can create.
Marquee - The Marquee contains the text content and some operational settings.
Marquee Style - The Marquee Style contains the visual styling (fonts, colors, etc) and location of the Marquee.
Create a Marquee Style - Use the Marquee Style Editor to create a visual style for the Marquee. The style can be applied to any number of Marquees.
Create a Marquee - Use the Marquee Editor to create a Marquee. Here you will apply a Marquee Style to the Marquee.
Assign the Marquee to a Media Item - Select a Media Item, then go to Edit Media Item > Marquee of Selected Media Item > Set to Standard Marquee (there is also a toolbar button for one-click access). From the resulting popup dialog, pick a Marquee.
Play the Media Item - Now just click the Play button to play the Media Item. The Marquee will appear on the Media Screen in front of the playing video.
Menu Locator: Media List Editor > Tools > Marquees .
Manage Standard Marquees - Allows you to Add a new Default Marquee; Duplicate (copy) an existing Marquee; Delete a Marquee. Select a Marquee, then click Edit to open it in the Marquee Editor.
View a Standard Marquees - Pops up a list of Marquees so you can view the Marquee settings.
Create Logo Marquee - Creates a simple Logo Marquee with a logo image and text. You are prompted to enter both values. Once created, you should edit the Marquee to pick an appropriate Marquee Style. See the Logo Marquee section for details.
Manage Timed Messages - Timed Messages are a special form of Marquees, but they use the same Marquee Styles as Standard Marquees. This menu item has the same 'Manage' functions as Standard Marquees.
View a Timed Messages - Select a Timed Messages to view its settings.
View All Media Items with Marquees - Pops up a list of all Media Items that contain a Marquee.
Pick Global Marquee - Pick the Global Marquee from a list of all Standard Marquees or Timed Messages.

Add Standard Marquee to Load Templates - Add a selected Marquee (pick from Standard Marquees or Timed Messages) to a set of Load Templates. (see Marquees and Load Templates section below)
Remove Marquee from Load Template(s) - Remove Marquee reference from a set of Load Templates.
You can use a Global Marquee that will apply to all Media Items that do NOT have a Marquee specified. This may be useful in cases such as displaying a small branding signature in the corner of videos (ie company logo, event logo, etc).
How to use the Global Marquee
Select the current Global Marquee by picking a new Marquee from Tools > Marquees > Pick Global Marquee
When a Marquee references a Marquee Style cannot be located, the Default Style will be used. This could happen if the referenced Marquee Style got deleted. You can change the Default Style any time with the Pick New Default Style menu item (see above).
To show a Marquee when using a Load Template, you need to add the Marquee directly to the Load Template before playing the first Media Item with the Load Template. Use the Add Standard Marquee to Load Templates menu item (see above).
Remember that all the Media Item's attributes are ignored when playing it with a Load Template. Thus even if the Media Item already specifies a Marquee, it will be ignored.
