The + (plus) on an Action Button typically indicates that it creates a new item in that area.

1. This can be seen in the folder tree to the left of the window, where clicking the Action Button will create a new folder within the selected folder.
2. Similarly, clicking the Action Button in the Version-Documents area will create a new Version Document within the selected Project.

NOTE: Sometimes, creating a new item requires uploading the item. For example, in the Font Packages Dialog, adding a new Font Package requires uploading the zip-archive file containing the fonts.

If there are multiple actions available rather than just a single action, the Action Button contains a kebab menu (3 vertical dots).

1. This can be seen in the Action Button for Projects, which opens a menu containing two actions: Create Projects and New Book.
2. When multiple items are selected, clicking the Action Button opens a menu of actions, allowing the user to perform bulk actions on all selected items.

NOTE: The number of selected items is displayed in the corner of the Action Button, helping the user to be certain that the correct number of items are selected for the action (e.g. if you think that you are deleting 2 items, but the number says 3, you should check for the extra item you have selected).
